Q: | Is there a way to use TI89's Lists or Matrix, so I will be able to keep information like high score or something else...
A: | Yes, more info about this can be found in this release of TIGCCLIB documentation (note that a matrix is a "list of lists"). However, using lists or matrices is somewhat complicated. It is much easier to keep information in a user-defined format. See the next question. A stdio.h header file is implemented, which supports ANSI C compatible file handling, so creating files is quite simplified. If you want to bypass stdio.h and use low-level TIOS routines (such an approach leads to smaller programs), see SymAdd.
