NULLSTRPTR mit NULL() oder mit SYSNULL() - memory leak

Description:
When a structure with a null string ('') is initialized, then all fields
of the structure will be initialized as well.

Sample:
POINTER fields will (with compiler option NULLSTRPTR) be filledwith
NULL() or SYSNULL(). Such assignments cause a memory leak in our system
because the value of POINTER is overwritten.

Suggestion:
It would be nice, when NULLSTRPTR option would get a new parameter like
NULLSTRPTR(INCOMPATIBLE).

When you would use this parameter for the PL/1 compiler, then it should
be forbidden that a null string is assigned to a POINTER.

This function would be compatible with the old MVS PL/1 Compiler.
