Calls to Other Routines
DMKPTRFR - CALLED TO OBTAIN A PAGE FROM DYNAMIC PAGING AREA
IF IT IS NECESSARY TO CALL DMKPTRFR TO OBTAIN A
PAGE FROM THE DYNAMIC PAGING AREA AND DMKFRE WAS
ENTERED AT ENTRY POINT DMKFRERC, DMKPTRFR WILL
BE CALLED WITH 'PARM = 2' TO INDICATE THAT IF
A PAGE CANNOT BE OBTAINED, A CC=1 SHOULD BE
RETURNED TO DMKFRE INSTEAD OF ABENDING VM/370
WITH A PTR07. DMKFRE WILL THEN RETURN THE SAME
CONDITION CODE TO THE CALLER SO THAT AN APPROPRIATE
ERROR MESSAGE CAN BE ISSUED.
