Is there a simple way to tell if slTest has been assigned in the

When slTest is a local variable, you should initialize it to Nil.
Otherwise the variable contains garbage, that most probably is *not*
Nil, so that FreeAndNil tries to free something that never has been
created.
Shall do - Thanks for that
