This program is a text viewer program.

There are the program's features :
- display any TI92+/TI89 text about 15 times faster than in the Text Editor
  ( I think this is the fastest text viewer).
- support pictures into your text files and EVEN compressed pictures (with ziplib
  or ziper.exe provided with doorsOS)
- use formated text : invert, underline, vector, fonts, margins,....
  (compatible with Xetal's format)
- text's breakpoints
- search command
- fast text browser
- can be ran from any TI-BASIC prog
- view compressed text (compressed with ziplib or ziper.exe provided with doorsOS)
- pprider : a program that converts formulas in the PrgmIO to PIC files
- fully compatible between TI89 and TI92+ 
  (you can even send the program from one calc to another)
- Pretty Print support

----------------------------------------------------------------------------------

* To run txtrider, you have three choices :
  1) Just run txtrider by typing txtrider() !
  2) Run it from an asm prog by pushing the handle of the text at the beginning of the prog   
  3) you can enter this command from the HOME screen or from any TI-BASIC prog :
   textview_fold\txtrider("txt_fold\txt_name")       txt_fold : folder name of the text file
               				             txt_name : text file name
            					     txtrider_fold : folder of txtrider
  But, why using this third method ?
  Because you'll be able to add this command into a Ti-Basic program and to make text 
  organizer.
  There is an example of a template TI-Basic prog which uses txtrider :

	Template()
	Prgm
	Local ch
	Lbl deb
	0»ch
	PopUp {"Text1_description","Text2_description","Text3_description",...},ch	
	If ch=0 Then
	Stop
	ElseIf ch=1 Then
	txtrider_fold\txtrider("txt1_fold\txt1_name")
	ElseIf ch=2 Then
	txtrider_fold\txtrider("txt2_fold\txt2_name")
	ElseIf ch=3 Then
	txtrider_fold\txtrider("txt3_fold\txt3_name")
	...
	...
	...
	EndIf
	Goto deb
	EndPrgm

	txt#_fold : folder of text#
        	txt#_name : text# name
	Text#_description : a short description of text#
	txtrider_fold ; folder of txtrider

UNHUFTXT:

thgis little progie allows you to convert texts from Hufftext's format to TI text file format.
Tgus, you can edit texts of which you have lost the original version.
The syntax is easy: 
From HOMe screen :

unhuftxt("folder\nameofthetxt")

----------------------------------------------------------------------------------
That's all ???
Nope !
There are lots of other informations included in the riderhlp file : 
- how to use formats
- how to read pictures
- how to put breakpoints

So, you'd really read it too !

----------------------------------------------------------------------------------

* History :
-----------
v1.0ß96: the browser remembers last open file
	 slow down when displaying pictures (which were displayed too fastly)

v1.0ß95: Only one way to run txtrider for every ROM version (the old one)
	 A few bugs correction

v1.0ß9 : Corrections of few bugs (not displaying pictures, ... )

         letter of the file you want to edit
         Some optimisation
V1.0ß5 : More optimisation
         You can now move faster into breakpoints by using the [2nd] key
V1.0ß4 : Some optimisations (size reduced by 1 KO)
         Correction of some bugs (Pretty Print)
V1.0ß3 : Added compatibility with ROMv1.05
	 Support compressed pictures (with ziplib)
