TI Tips Book
In an effort to provide easily accessed documentation to TI users, I have put together a TI tips booklet that consists of 99 tips for the TI-99/4A. These are a compilation of suggestions given in our user group newsletter. They include PEEKS, POKES, listings, hints, and so on. Also included is a complete disk drive memory map, summary of Extended BASIC commands, and a sorting program written in BASIC and machine language. One such tip that may interest your readers allows them to disable FCTN = (QUIT) in Extended BASIC. To do this, enter this statement:

CALL INIT :: CALL LOAD(-31806,16)

    To enable it again, type CALL LOAD(-31806,0). Another POKE allows you to prevent Extended BASIC programs from being listed. Type CALL LOAD(- 31931,128) to do this. To unprotect Extended BASIC programs, enter CALL LOAD(-31931,0). The TI tips booklet is available through the Central Iowa 99/4A Users Group for $4 (the cost of materials, printing, and postage) at the following address:
