Here is a way to get around that:

type intpointer = ^integer;

function intptr : intpointer;
var i : integer;
begin

   writeln('test');
   intptr := @i;
end; { intptr }

If you make a new type and use it as the return value it works.

Another question I have is what is the exit condition for the program? Does
the program exit cleanly if given empty input or maybe the word "quit"? The
spec doesn't seem to say.

Thanks, Matthew
