I'd like to use a constant record as a default parameter. Is there some way to
do this? Here's my use case:
type
lt_ints = record
left, top : longint;
end;
const
lt_zero : lt_ints = (left:0; top:0);
procedure do_something (const offset_lt : lt_ints = lt_zero);
The procedure declaration gives an error ("illegal expression").
I assume the trouble is that lt_zero cannot be used as a default parameter
value, because it is not truly a constant: it is an initialized variable.
Perhaps my real question is: how do I make a constant record which is truly
constant, rather than an initialized variable?
Thoughts?
Thanks :-)
