Inferno v1.0

** ABOUT

Inferno is an 99% Ion compatible shell for the 83+. It runs Ion programs. 


** INSTALLATION

Send INFERNO.8XG to your calculator. The following programs will be transferred: A, INFERNO, ZINFERNO

You may archive ZINFERNO to save space, however you cannot archive INFERNO. If you do, INFERNO will only use 990 bytes of RAM.


** USAGE

Run prgmA to start Inferno.

The following keys are valid in Inferno:

Left/right arrows - change screens of programs
Up/down arrows - move through the program list
Mode - exit Inferno
2nd/Enter - run currently selected program
On - power off calculator
F1-F5 - change to folder
Prgm - move current program to folder (press Prgm followed by F1-F5)

** WHY YOU SHOULD USE INFERNO INSTEAD OF ION

Inferno provides 99% compatible Ion emulation, allows support for folders, and is smaller than Ion if you archive ZINFERNO. Why not use it?


** OTHER

You must have enough free RAM equal to the program you are running. Example, you must have 3K free to run a 3K program in RAM. This doesn't really matter, though, as many people leave all of their programs (games) in the archive.

** INCOMPATIBLITIES

While Izzard is completely compatible with Ion, ZTetris will crash Izzard because it uses RAM areas not defined correctly in ion.inc. There's nothing I can do about this, contact the authors of ZTetris and ask them to use saferam1 instead of the statvars. This is why I list Inferno as 99% compatible.
