EXECUTION:

_______________________________________________________________________________

Yapt is nostub. It requires no kernel or libraries. So send it to your

calc and run it. Due to restrictions ti has placed on asm programs you

will need to use a launcher to execute yapt on the new AMS versions greater

than 2.00 The Fargo version requires flib and graphlib. The 89 version of

yapt will not behave properly on VTI. If I felt like it I would add code to

yapt to compensate for Vti’s improper emulation of the low power port but I

don’t feel like it.

Yapt can also accept arguments. When executed with arguments the program

will prompt for a chemical formula. See the part of the documentation which

details the chemical formula editor. This feature is not in the Fargo version.

I use this chemical formula editor feature from a kbd program, that is why I

decided that the interface to it should be passing an argument.

The Exepacked versions require ttstart, which is from the tigcc tools suite to

decompress and execute them. The tict file explorer has this ttstart built in.

Or you could let Ash apply the decompressor that comes with ash.

Remember to choose which label strings and which sub orbital coordinate system

and even the default atomic number one prefers before archiving. The ymaxs

used in the trait grapher are adjustable and are remembered when the program

exits, so set them the way you like before archiving.

Also on the 92+ version you should set the delay between arrows of yapt before

you archive it. Do this with the ‘+’ and ‘-‘ keys.

There are a couple standards as to how

they should be ordered. Of course I

use the standard in my chem. textbook.

To see the other standard press clear

this data item found at http://www.webelements.com/ says that

many sources cite this data item for group 1 and 2

greater than those given at webelements- webelements was

not my source and the values given in yapt do not always

agree with webelements. Webelements also cites a few

other elements which there are measurement inconsistencies

floating around.

2- through 3+ Ionic radii* ->remember that these vary according to geometry.

The geometry for the values given is often the

six coordinate octahedral. But that is not

guaranteed.

It might be the case where your text book will

Give data that is different from that of yapt’s.

Before doing any calculations with the data in

yapt you should check to make sure that it is

consistent with you text book. This goes extra

for the ionic radii.

KEYS ON ALL DATA PAGES:

_______________________________________________________________________________

right or left arrows-> Increase or decrease the atomic number. And if on the

main data page the cursor will move. On the 92+ any program which

modifies the general key repeat rate will also modify yapt's cursor

repeat rate.

---If two keys are given the second key given is used in the 92+ version---

apps-> Display the electron data page unless already on the electron data

page.

backspace or enter-> Display the third data page unless already on the

third data page. Backspace can auto repeat like an

arrow so do not hold this key down for too long.

Catalog or f8-> Go to the Custom Data Page. See the documentation of

this data page.

esc-> Exit the program, yapt will remember where it is on the chart.

f1-f3-> Smart searches.

f4-> About page.

f5-> Toggles between two labeling systems. The user can choose between

descriptive labels OR non-descriptive labels with units. Yapt will

remember the users choice. This will have no effect on the third

data page.

Diamond or Ln-> Enter individual export mode, the user can pick any numeric data

item on the screen and store it to the clipboard or to the history,

read below for more info. This feature is not in the Fargo version.

"x" or sin-> Enter molar mass computator.

"y" or cos-> Difference between electronegativity computator.

"z" or tan-> Quiz for element names, will give the symbol. See quiz section.

"t" or "^"-> Quiz for element symbols, will give the name. See quiz section.

"^" or "/"-> Goes to the data property grapher.

2nd or f6 -> It will place the atomic mass of the current element into the

clipboard and immediately exit. This feature seems useless but

it is occasionally useful for some questions on chem. tests.

This feature is not in the Fargo version. It was put in to aid

manual molar mass calculations for testing and debugging the

molar mass computator.

shift or f7-> Export data. See the section on data exportation. This feature

is not in the Fargo version.

On the 92+ the ‘+’ key will increase the delay between auto-repeations of the

Arrows/backspace.

On the 92+ the ‘-‘ key will decrease the delay between auto-repeations.

Any other key will return the user to the main data page.

KEYS UNIQUE TO THE MAIN DISPLAY:

________________________________________________________________________________

up and down arrows-> Move the cursor up or down.

clear-> Changes between two ordering standards for the

abbreviated electron cloud diagram.

KEYS UNIQUE TO THE ELECTRON DATA PAGE:

________________________________________________________________________________

clear-> Will cycle between three coordinate systems for the electron

sub orbital diagram. The default is the one in my chem. text

book. It will remember which coordinate system was chosen

when you exit, so be sure to set it the way you like before

archiving.

The second coordinate system is like the one in Elements for the

ti86 and is seen in a few other places like at http://www.webelements.com/

that also uses arrows to depict electron spin and pairing. The second

system also allows the user to see the relationship between the

suborbitals and the bohr model better than the other two.

The third is a one-dimensional diagram. I put it in because I saw

that someone had made a basic program for the 89, which did the same

thing. There is a standard that has them in another order, but

my chemistry textbook does not use that standard.

KEYS UNIQUE TO THE THIRD DATA PAGE:

________________________________________________________________________________

NONE

CUSTOM DATA PAGES:

_______________________________________________________________________________

The data for each custom data page is an external text file. These text files

must be in a folder named "zzcnotes". The name of the text file for each

element is simply the symbol of that element. The data of the text file will

be printed on the data page. It only allows for 1 full data page and there

is no word wrapping.

On the 92(+) the name will be printed in the status line along. All models

will have the symbol/number arrow combination.

SEARCHES:

_______________________________________________________________________________

f1-number search.

f2-symbol search.

f3-name search.

In the number search type in numbers, if you type a number greater than 11

yapt will automatically take you to that number. If you type a number less

than or equal to 11, press enter to go to elements 1-11. If you type in a

third number then you have inputted a number greater than 11 and so it will

automatically take you to that number.

In the symbol and name search type in characters. Do not hit the alpha or

shift modifiers. If for example you want Hydrogen, after typing in the "H"

hit enter. It doesn't know yet if you want Hydrogen or if you want Helium.

Any time an inappropriate key is pressed in the searches it is ignored. And

if a letter is pressed which does not narrow the search then the letter is

also ignored: therefore it is impossible to input a non-existent name,

symbol, or atomic number.

The escape key will exit a search, backspace will remove the last key pressed,

and clear will get rid of everything typed in.

MOLAR MASS COMPUTATOR:

________________________________________________________________________________

In the molar mass computator first type in a symbol; do not worry about upper

and lower case. To input a one letter symbol just press enter after the

symbol and the cursor will move into the subscript OR type the letter of that

one letter symbol a second time. It will automatically bring the user into the

subscript if the user enters a unique symbol.

Note: It will now prevent the user from entering a non-existent symbol.

This protection is not complete. It will still let the user type

in partial symbols. See the history for a couple examples.

The limit on the subscript is 2^16-1 (65535). IT WILL PREVENT YOU FROM ENTERING

A SUBSCRIPT THAT IS TOO BIG. When done entering the subscript press enter and the

cursor will move back up to enter the next symbol. If you do not wish to enter a

subscript press enter and the cursor will move up for the next symbol. Continue

entering symbols and subscripts in this fashion till you are done.

The molar mass computator also supports nested parenthesis. A parenthesis may

be inputted while the cursor is in the subscript or the normal line. All

parenthesis must be closed in order to evaluate the molar mass by pressing

apps and something has to have been entered to evaluate the molar mass. ON THE

89 YOU ENTER A "(" WITH THE 2ND BUTTON AND THE ")" WITH THE GREEN DIAMOND

BUTTON.

To evaluate the molar mass press apps. The molar mass will be calculated and

displayed. The calc will then idle. The user may press apps again to store

the result directly to the home screen history. Storing the result to the

history is not supported in the Fargo version. Storing the result to the

history will activate the home application, but most likely the home app was

already activated.

Or once the molar mass is evaluated you can store a matrix that has the percent

composition by mass of each element to the history by pressing f1. Or if you

press F2 it stores the percent compositions for each element individually from the

others as history pairs. If you will be doing calculations with these ratios then

this second method is better because it provides easier access. (just scroll through

the history to get it) Regardless of which option you choose it will still store

the computated mass along with the ratios. And it will store the formula as an

entry. The percent compositions by mass for each element will will be stored in

order of atomic number.

The form of this matrix is as follows:

[[ “MASS:” massOfCompound ]

[ “Elem1” massOfElem1InCompound/MassOfCompound ]

[ … … ]

[ “ElemX” massOFElemXInCompound/MassOfCompound ]]

[Backspace] will backspace, [escape] will escape, and [clear] will clear. [Home]

on the 89 and [diamond] + [v] on the 92+ will paste stuff in from the clipboard

into the molar mass calculator. This is not in the Fargo version. This

feature is also available in the chemical formula editor.

The user may not type more than 150 characters on the screen at once.

If the computated molar mass goes above 9999999999999999.99999999 the user

will receive an overflow error. This is more than tios's floating point

computations can handle so when storing results to the history it is possible

to loose some digits. If the user tries to evaluate a molar mass with a

non-Existant symbol, or a character that is not allowed (Chemical Formula Editor),

or a mass which causes an overflow an error message will be printed, and the entered

formula will be placed in the clipboard, so that you may then try again and edit out

the mistake.

CUTTING IN THE MM COMPUTATOR:

_____________________________________________________________

Suppose that you enter a very big formula and see a mistake

at the beginning and need to correct it. Now I am too lazy

to implement an insert cursor mode so instead yapt will allow

you to cut off the end of the formula, fix the mistake, then

paste what you cut off back on.

To do this press the left arrow and keep pressing it until

You have highlighted everything that you wish to cut off.

The highlighting is a bit odd. It highlights everything

until it hits an uppercase letter, a ‘+’, the store arrow, or

either of the parenthesis.

When you are done highlighting you press [apps] to cut the

text away. Press [escape] if you decide that after all you

do not want to cut anything. Press [clear] to delete the

highlighted text. [backspace] will not delete anything.

Pressing right will un-highlight stuff.

Yapt will use the tios clipboard to store stuff so after

you exit yapt you can paste text if you so desire.

This feature is not in the Fargo version.

Of course this all applies in the chemical formula editor.

EXTRA NOTES FOR ONLY THE 92(+) OWNERS:

______________________________________________________________

It is no longer necessary to press enter to go in and out of

the subscripts. If you type Letters while in the subscript

(or the exponent in the formula editor) the cursor will move

into the normal entry line and the letter will be displayed.

If numbers are entered in the normal line then the cursor moves

into the subscript and the numbers are printed.

If you wish to enter a 1 letter symbol with no subscript type

the symbol, press shift, and type the first letter of the next

symbol in uppercase. Meaning that you do not have to go in

and out of the subscript.

EXTRA NOTES FOR THE 89 OWNERS:

_______________________________________________________________

If you want the next letter you input to be uppercase you can

press the up arrow. You no longer have to go in and out of

the subscript to enter one-letter symbols. If the up arrow is

pressed while the cursor is in the exponent or the subscript

then the cursor will move into the normal entry line.

Similarily Pressing down will force it into lowercase mode.

If you want Hydrogen with a Subscript, you can type an H and

then type another h and the cursor will move into the subscript.

This means that you do not have to move your thumb over to the

enter key and press it to move the cursor into the subscript.

This also applies to Carbon and other one-letter symbols.

The "(" character is mapped to the 2nd modifier and the ")" is

mapped to the diamond modifier.

The character mode is printed in the lower right corner.

Even in number mode the keys with letters not on the number keys

still behave as letter keys! For example if you typed "Ca45" the

cursor would be in the subscript. If you then hit the "=" button

the cursor moves instantly out of the subscript the character "A"

is placed. In this case you did not have to press [enter] to first

move the cursor out of the subscript. So now the only way to type

parenthesis is with the [2nd] + [diamond] buttons, and you must use

[shift] and [alpha] to enter the store and plus characters in the

chemical formula editor.

THESE EXTRA NOTES ALSO APPLY DURING THE CHEMICAL FORMULA EDITER.

CHEMICAL FORMULA EDITER:

________________________________________________________________________________

I downloaded the Alchemistry package released by Alex Astashyn. (To get it go

to the download area of: http://sq.calc.org)

After familiarizing myself with the programs in this package I decided that

after using the molar mass computator described above I really hate to type

in the formulas in the entry line.

So I re-wrote the molar mass editor to be more like an event driven program.

There are now two drivers for this program the first is used to input the molar

mass and then evaluate it. The second allows more stuff like inputting exponents

for ions, the plus character and the store character, and the negative sign when

inputting a negative ion.

Here is the syntax when passing arguments to yapt:

yapt(arg1,["appendString"])

If the append string argument is present then the output will be preceded with

the append string and it will end with a ")" For example the append string

could be "chem\chembal("

If there is no append string argument present, then the output will be only be

enclosed in quotes.

Arg1 can be either a string or anything else. If it is a string then yapt assumes

that it is a formula that user wants to re-edit. If it is not a string then a

blank editing session is started. And if that string is the output of chembal,

then the output is pretty printed.

When done press apps and the entered formula will be placed in the clipboard

and the program will exit. Then paste the string as an argument for the balancing

function or the molar mass function both provided in the Alchemistry zip package.

On the 89 shift is the same as the store character and alpha is the plus character.

2nd and alpha work the same as in the molar mass computator.

The chemical formula editor is not in the Fargo version.

DIFERENCES FROM THE PREVIOUS VERSIONS:

_____________________________________________________________

You CAN use it to view the output of the chembal program.

It now applies smart limitations to formulas the user is

re-editing.

There is the append ability.

You can now press f1 to apply the molar mass computator. It

will not export anything to the clipboard, but you can still

store results to the history. If it encounters an exponent,

a plus or store arrow, an error will be printed and the calc

will idle.

It now allows for entering coefficients. To do so press the

Right arrow. It will then allow numbers in the normal line

(as opposed to the subscript or exponent) When done with the

coeffient press enter or type a letter. (remember that even

in number mode on the 89 you can still type letters on non-

number keys) It will restrict you from entering coeffients

when you should not.

Press f3 for (aq), f4 for (s), and f5 for (g). The aqueous

symbol is stored as char 0xFD, the solid symbol is char 0xFE

and the gaseous symbol is char 0xFF. The chembal program from

the alchemistry package will not recognize them as state symbols

so do not put them into formulas that you would be balancing.

DIFFERENCE BETWEEN ELECTRONEGATIVITY COMPUTATOR:

__________________________________________________________________________________

This was a feature on a ti86 assembly program that I use to use and now it is

replicated here. It will use the symbol smart searcher to request the elements

to find the electronegativy difference between. It will print the difference,

and the bond associated with that difference. Then it will calculate the %ionic

character with the following formula:

(1-exp(-(0.25)(CalculatedDifference)^2)) * 100

Then the calc will idle. And the user will get various history storage options

for the results.

If one inputs the symbol of an element whose electronegativity is unknown then

an error message will be displayed and the user must input a different symbol.

SYMBOL/NAME ASSOCIATION QUIZZER:

________________________________________________________________________________

Depending on which button is used to enter the quizzer the user will have to

enter symbols given a name OR will have to enter a name given a symbol. If

the user enters an incorrect symbol/name the user will then have to try again.

If the user wishes to give up just press escape. The answer will be printed.

If the User is done press escape again, or press anything else to continue

being quizzed.

DATA TREND GRAPHER:

_______________________________________________________________________________

The user will first be presented with a menu to select the numeric data item

the user wants graphed by moving the marker (which is a small box) to the data

item and pressing enter. It will then be graphed as a scatter plot and the

calc will idle. The first tick of the x-axis is x=zero, ticks are then placed

with x increments of 10.

Unknown data items are graphed at y equals zero and all marks are placed with

xor logic so unknown items and known items with values that cause it to

fall upon the x-axis will delete part of the x-axis. If a value is greater

than the ymax then it is placed at the top of screen rather than off the

screen.

The up key will increase the ymax variable, and each graph has its own ymax

variable. The change will be remembered when done, so set the ymax variable

to how you like it before archiving, else it will not be remembered. The down

key will decrease the ymax variable. There are limits as to how far ymax may

be increased or decreased. Ymax will be printed in the lower right corner

with a label. A tick mark is placed at ymax.

The "^" or "/" key will take the user back to the menu to pick another trend

to graph. The key depends if the user has a 92+ or an 89.

Right and left arrows move the trace cursor right or left. F1-F3 do smart

searches, the results of which will move the cursor around. And escape

returns the user to the main table part. The elements name and the numeric

value used as the y coordinate (the x coordinate is the atomic number) will be

given at the top of the screen. The symbol and atomic number will be placed

between two arrows pointing left and right like on the non-main data pages.

The units of the data item will be displayed at the top of the screen.

Press diamond/ln( to store the stuff at the tracer of the graph to the history.

DATA EXPORTATION:

_______________________________________________________________________________

Press shift on the ti89 or f7 on the ti92+. This feature is not in the Fargo

version. The user will be presented with a menu to select the data item to

export. So select an item. Values whose data elements are unknown are given

in the list as undefined. It will then tell the user the name the list was

created to. The idea is that the user will be able to put the data through

various data analysis.

The variable will be made in the current folder. If you archive a list and

then have yapt export the same list odd stuff may happen. I say that this

is a stupid thing to do.

It will also make a list of the atomic numbers called "atm_num"

INDIVIDUAL EXPORT MODE:

______________________________________________________________________________

To use this feature press diamond on the 89 or ln( on the 92+. This feature

is not available on the custom data page and it is not in the Fargo version.

First you should try it on the main data page. The first thing you should see

is that the label of hardness is now printed inversely: This means that hardness

is selected.

Press the down and up arrows to change what is selected. Down moves the

selector in the "forward" direction. Up moves the selector in the "backward"

direction. When you have selected the numeric item you want press the left arrow

to export to the history. Press the right arrow to export to the clipboard and

immediately exit yapt. If you decide that you do not wish to do either of these

two things then press escape to go back to normal browsing.

If you choose to export to the history, units will be added. It uses predefined

Units whenever possible, but in some circumstances it is not. There is a predefined

joule unit, but no Kilo joule unit so for kj/mol it uses the unit (1000 * j/mol).

The 1000 will not be evaluated out of the expression when it is put to the history.

I do not want it to. If I evaluated the expression then measurements like angstroms

will be converted to the default length measurement unit of Meters (and I want it to

be in angstroms), of course you could change the default to Angstroms but I doubt that

you would want to.

The selector moves from item to item in the order that they are stored. So on

the main page the movement will be random, I could redo the layout of the data,

but I like the way it is positioned now. Or I could redo the entire structure

in which the data is stored but that would be very tedious and very long, so

you shall have to suffer.

Also on the electron data page you cannot select the electronegativity, to

do so you must select the electronegativity while on the main data page.

If you are too lazy or love efficiency, shortcuts have been provided so that you do

not have to actually scroll to the data item you want. The shortcuts are positioned

on the keyboard to be similar to how the data is positioned on screen. For example

the electron affinity is on the left edge of the screen so the shortcut for the electron

affinity data item is on the left side of the keyboard. The electron affinity is

positioned above the heat of vaporization on the screen, so the shortcut for the

electron affinity is positioned above the shortcut for the heat of vaporization.

Now hear they are: Note that on the 89 the keyboard will be in alpha mode but there

will not be any indicator of the alpha mode printed.

Alternatively there is another way to store numeric data items to the history.

Go the element whose data you want to store. Then start the data trend grapher

or the data exporter. Move the cursor to select the data type you want to store

and when the cursor is there press diamond on the 89 or LN( on the 92+ to store

to the history.

FUTURE PLANS:

_______________________________________________________________________________

More data.

Maybe an argument passing mechanism that lets the user specify an element and

which datum wanted and yapt will return it.

Any random improvement I might happen to think up ;) This might be the last

release, I’ll see what happens.

Translations to other languages; help needed.

CONTACTING THE AUTHOR:

________________________________________________________________________________

Please send questions, comments, and bugs to me at sstear70@calvin.edu. When

reporting a bug be specific as to how it happened, and describe your system-

Calc, Hardware version, AMS version, Kernel and Kernel version. Also tell me

How yapt was launched.

Yes I know that the 89 version of yapt will not work properly on VTI. Get a

92 plus rom to emulate it.

If you send suggestions then know that I really like the interface so do not

tell me that it is not graphical enough. Do not ask me to add more data. I

know there is more data and I will add it in my own time if I chose to do so.

If you do not understand certain data items because you have not learned about

them in school then do not ask me to explain them.

THE FINE PRINT:

_________________________________________________________________________________

Yapt may be distributed anyway possible without permission as long as no profit

is made off of that distribution. If profit is being made on such a

distribution then my permission is needed. This includes but is not limited

to CDs, floppies, and downloads off of an internet or ftp site. I only plan

to upload to the major ti (calc.org, ti-fr.org, and ticalc.org) archive sites.

Yapt may not be distributed in another package or ever be made to look like it

was written by somebody else.

Do not separate the files in this zip archive or distribute a modified version

of this zip archive.

The code is open source, I hope others can learn from it. Any program that

uses any code from yapt must be open source. And for the sake of version

control please contact me if you plan to add more to yapt.

I am not responsible for any crash, damage to calculator, or loss of data that

might result from the use of yapt.

I do not guarantee that the data given in yapt is correct and I am not

responsible for anything that is done based on incorrect data.

Some data is owned and copy written by the Journal of Chemical Education and

may only be redistributed with their permission. Their website is at:

http://jchemed.chem.wisc.edu/

The NMR frequency data belongs to MIT and needs their permission to be distributed.

Here is the url for said data: http://web.mit.edu/speclab/www/nrfreq.html

-Florian Joffrin for the French Translation.

-The Journal of Chemical Education owns and provided a lot of data on

Chemicool and they gave me permission to distribute data on Chemicool.

Their website is http://jchemed.chem.wisc.edu/

-David Hsu for http://www.chemicool.com. This was my primary source.

-Gareth James for his history/home application documentation.

-Zeljko Juric for all his Tigcc documentation which I have enjoyed reading

through.

-Rusty Wagner for VTI.

-Alex Astashyn for his Alchemistry package. This is available at the

download area of http://sq.calc.org/

-JL for prdc86p, Andrew Hockman for Elements, and Stephen Hicks for chem86.

I used these programs when I had my 86 and their influence is in yapt.

Of course I also took features from the 83plus flash app periodic table,

so maybe some thanks should go to TI.

-Jimmy Mardell for writing a very extensive 68k guide, and line library

code.
