01 SILLY-POINTER USAGE IS POINTER.
or
01 POINTERS-AND-OTHER-STUFF. 05 SILLY-POINTER USAGE IS POINTER. 05 SILLY-VALUE REDEFINES SILLY-POINTER PIC S9(8) COMP.
Set pointer variable
Set from a regular variable
SET SILLY-POINTER TO ADDRESS OF RECORD-1.
RECORD-1 is a general variable in Working-Storage Section.
Set from another pointer
SET SILLY-POINTER TO SILLY-POINTER2.
SILLY-POINTER2 is another pointer type variable; so SILLY-POINTER and SILLY-POINTER2 point to same address.
Set to null
SET SILLY-POINTER TO NULL.
