AND OR
One omission from TI Basic is the lack of logical operators such as AND and OR used for example in expressions such as IF V<8 AND W>4 THEN 120 ELSE 240. TI Basic programmers instead used mathematical operators to replace logical operators.
Check Alpha Lock
A program using the joysticks requires the alpha lock is UP, a relic of the TI99/4 days.
If your program requires the alpha lock to be DOWN for input etc you can instruct the console:
Insert a dummy line CALL KEY(3, Z, Z)
The use of key unit 3 tells the computer to treat the alpha lock as if it were down whilst the program is running, unless we reset. Use of key unit 0 has no effect on alpha lock status. Key unit 5 will reset normal operation.
