How can you run several programs at once on a TI-83?

Answer 1

You have to make sure that your program runs smoothly. Make sure that the program does not get tangled up in too many Lbls and Gotos. Running several programs at once does not mean executing them all at once, but it simply running several segments at once. For those who know how to program a TI-83 or TI-84, you can try incorporating this program into yours. It is basically a number counter that will act like a timer while you execute another program. I put the coordinates as 0 and 89 so that the timer will end up in the corner of the screen, rather than someplace in the middle.

ClrDraw

0->A

Lbl 1

Text(0,89,A)

A+1->A

Goto 2

Lbl 2

(Here, you can put all your other game stuff in this space. If you are using any key presses, create a segment something like this)

Getkey->G

If G=22:Then

(Here, you can stop the program entirely with these function)

ClrDraw

Stop

(Or you can make it go to another segment of coding. If that's the case, then use this command)

Goto 3

(from there, do whatever else you like)

(Otherwise, if you want to return to the timer, then do this)

Else

Goto 1

(Or if you have other keys you want to press, then do this)

Else

Goto 4

Lbl 4

If Getkey=25:Then

(and so on. Don't forget to add the 'Else' command later in your program.)

Getkey can be mapped out on your calculator buttons. 11 is the first number, which is the 'Y=' button.
