In Pascal, Assigned() is a Boolean function that you can apply to anything,
to determine whether that "thing" has an address in memory.

From the VCL help:
Use Assigned to determine whether the pointer or procedure referenced by P
is nil. P must be a variable reference of a pointer or procedural type.
Assigned(P) corresponds to the test P<> nil for a pointer variable, and @P
<> nil for a procedural variable.

Assigned returns False if P is nil, True otherwise.

Maybe you're bumping into a pointer problem in C++?
