Okay, well I haven't done a whole lot of looking over your code yet. So these are just basic things so far.

First I might suggest to put it all into one program. It's easier to deal with when giving it to other people and groups can get wonky sometimes. Just a suggestion.

prgmNAME could be changed too

a+bi
Full
ClrHome
Disp "MY","NAME","IS","FRIDAY
rand(15
ClrHome
Disp "THE","SERIAL","TIME","KILLER.
rand(15
ClrHome
I don't know if the Disp changes affect the size any but ya. But I'm not sure why you had the If dim(rand(15)) lines. If it was just a pause effect then all you need is the rand(15). The If statement is unnecessary because the dimension of the list created will always not zero since your declaring the size to be fifteen elements.

As for prgmDELVAR I would suggest only make it the variables you use or just get rid of it all together. I just mean to run it at the beginning seems kind of redundant if you're going to be replacing all those values with the starting values and all. As it is nice to clean the program up with that type of thing it isn't necessary so it will be your call. I'll look over the rest of the code of the main program when I get a chance.

Are you asking for help with TI-BASIC for optimizations, how to do something, etc. or are you more asking improvements for the game like functionality wise and such? If it's the second I think this should probably be moved into the projects sections.

For Jump? I don't remember but I think I learned it from looking at one of your games you gave me when I was writing my tutorial for basic jumping. Then when I was making the game I just remembered something and did a little research behind both those commands because I couldn't remember which one it was. I'm so far out of good practice right now though that I can't even remember what I did

It also could just take a little bit to fully update the final image, but I don't know. You'd have to wait until {AP} replies.

Which game is it a hack of? And what's the link to it?

What do you mean does it look sweet? And it guarantees it because each command only takes up one element and since each list has 999 elements that's how many undos you have. The only reason you'd have less than 999 is if you had low memory and the list won't fit.

Bump.

Did that help, Freyaday?

Edit:
Can be optimized a little from just scanning over it.
