Hi,

Does the VP7 compiler unwind recursion internally or convert it to branches? For example, if I have the following code:

Code: Select all

pester() :-
  write("Say uncle: "),
  I = readLine(),
  if I <> "uncle" then pester end if.

Is the recursion converted to a branch or could this code potentially trigger a stack overflow if enough "wrong" inputs were entered?

That code will not cause stack overflow.
