Where's the function result?

I'm calling some code built with the Pascal calling convention modifier
from assembly, and I need to know where the function result will be
stored.  Where will an integral result be stored?  Where will a result
larger than an integer go?

Basically, I have code:

asm
call Function
end;

And I need to know where the result of Function() will be on the stack.
 Can anyone tell me, or should I just disassemble a program?
