Well, in a sense :-)  The address 16C5BF5032000000 is the address of the MI
pgm
itself (the one this MI code is in).  If you dump the MI pgm with SST, you'll
see
that the address 16C5BF5032001550 is in the "External object list table".
What
"exists" is a byte string in the MI pgm, not a pgm object named "BADNAME!!".

===> but that is the only thing the CMPPTRT instruction cares about. From
the manual: If operand 2 is null an equal condition occurs if
a pointer does not exist in the storage area identified by operand 1.

Nothing requires that an object exists just the pointer. No smiley needed.
