interesting, I wonder how fast will it be compared to using several dozens of delvar commands, since it is actually larger than those delvar commands? (81 bytes total for all 27 vars). Does it also delete archived vars?
ahh okay. Yeah, it's something about searching through the whole program list to find the asm program, right? So if you have a lot of programs, than it takes long time to load the program... Got it^^
Maybe this could be integrated in future Celtic III versions too? In hook form, it would eliminate the slowness of the Asm() command and be blazing fast. Celtic III games could run this when exiting so all unused vars are cleared

Mhmm strange I wonder if someone could help
I commented even more the source code and optimized further in size. (I think there is still some ways)I cleaned the source, added the defines and final tested.Now write the readme, do the batch files to compile , decide the program names and upload. The interesting now would be someone help me debug the TI-83 build. For the TI-83 there is few documentation on bcalls, but I will try to compare to TI-83+ to see what differences come out. Debugging on calculator and watch the entire bcall disassembly is a thing I won't do. Maybe it is not worth to put on TI-83 nowadays.
