Recursion?

[Jay Lundy]

I bet you could simulate a stack on RAM and get one with more size. It would take some work, and you would need to know some asm to do it, but I think it's entirely possible. Rather than using call to jump to the function, which pushes the PC onto the stack, you could just use goto, which just jumps striaght there. Storing variables gets harder though.

I doubt it's worth the effort. Just watch STKPTR<4:0> and make sure your recursive function stops recursing if it sees the stack is near full.
