RELPAGE 85 55 Provides support for the RELP AG macro. At
entry register 1 points to a list of 8-byte area.
Each entry contains the beginning address and the
length-l of an area to be released. A non-zero
byte following an entry indicates the end of the
list. An area is released only if it contains at least
a full CP page (4k bytes). Pages are released
when the virtual machine calls CP via DIAGNOSE code X'lO'. On return R15 holds return code as
follows:
R 15 = 0 all areas have been released
R15 = 2 one or more negative area
lengths were specified
R 15 = 4 one or more pages to be
released were outside the user
storage area
R 15 = 16 at least one entry contains a
beginning address outside the
user storage area. FCEPGOUT 86 56 No operation, successful return code of 0 is given
