I'm probably just being nitpicky here, but I'm trying to optimize some
turbopas routines.  Here's what I'd like to do:
function what(var where:string):string;
begin
   what:=where;
   what:=what+what; (* string concatenation *)
end;
Obviously, in it's current form, any compiler will probably attempt to
deal with the concatenation statement as a recursive function call, but that's
not what I'm after.  I'd actually like to reference the function return
buffer (on the stack) as a variable.
I tried something like:
var alias:string absolute what;
in an attempt to reference the buffer, but TP 5 acts like it wants the 'what'
to be an actual function call, which doesn't make much sense, since it's in
a non executable statement.  Anyway, does anyone have any ideas?

Thanks,
Rich Winkel
