No, that is not possible.
Except if your pointer is declared as a member of a class (which is
always assigned to nil by default)

I suppose that it isn't, but it would be to easy to resolve that trouble
that way.
Anyway, I appreciate your help and support.
Thanks.

You can assign "nil" to the pointer before using it, then check if PStruct =

I have something like this:
PStruct = ^Struct;
Struct = record
num: integer;
end;
I have a unit to handle that structure ( is a bit more complicated, but
is a good example), in this unit I have a procedure that deletes (
disposes ) the pointer. How can I know if a pointer a
13 matches
