Function command implementation

[asev98]

What does "Push 0" means? Does it mean push local 0 or pop local 0 for the new function's local segment? Or am I completly wrong and it means something else?

This means do the equivalent of calling your "push constant 0" code writer nVars times.

Another way to state this would be:
  fill RAM[SP] through RAM[SP+nVars-1] with zeros,
  set SP = SP+nVars.

What this operation does is reserve space on the stack for the function's local segment and initializes all the local variables to 0.
