TI-BASIC:Compatibility

When writing TI-Basic programs, it is ideal to have the program universally compatible with the entire TI range. But may be ideal is not always possible. For example, while there are no lowercase letters on the TI-83, excluding the statistical variables, all of the other calculators have them. Keep in mind that although the actual command may not exist on a calculator, it may be possible to transfer a program with the command to that calculator. Here is a table showing the TI-Basic commands that may provide compatibility issues between different calculator versions:
