how can I do the following on an 89?


This is code to update t, when the up or down key is pressed. down increases, up decreases. It also keeps t >=0 and <=21. Only problem is it doesn't work.

So, what I have now is:

If x=338
If x=344
If t=-1
If t=22

as far as i know, that's about as simple as you can make it on the 89.

you can use the when() function like this:
when(condition,isTrue Do: command,isFalse Do: command,isUndefined Do: command)

but i guess that's only applicable in boundary detection and similar things where you're only checking for one parameter instead of four.

you could use when(condition,1,0) to convert a true/false value to a 0 or 1.

Also, if this is the only way t can change, you could combine the conditions to be (x=338 and t>0) and (x=344 and t<21) respectively, and have two conditions less to check for.
