Re: Minimum Stack Size

Thank you all for your instructions, which make perfect sense to me. As 
you say, the default stack size on MacOS is 8 MBytes, which I think 
should be enough.

I want to reach a recursion depth of around 10,000. So long as each 
recursion consumes less than 800 bytes, I'll be okay. But the program 
crashes at a depth of around 2000, which suggests tht each time the 
procedure calls itself, it uses 4 kBytes of stack space.

If you have a minute, please consider the following:

procedure recursive(i:integer);
begin
   if i<2000 then recursive(i+1);
end;

Now, if I were programming this in assembler on a 32-bit machine, I 
would push the intereger and the program counter onto the stack, using 
eight bytes. Does GPC push all registers onto the stack for a procedure 
call, and if so, can this take 4 kBytes?

Yours, Kevan
