CSRPRFR — Return a cell to a cell pool (register interface) z/OS MVS Programming: Assembler Services Reference ABE-HSP SA23-1369-00 |
||||||||||||||||||||||||||||||||||||||||||||||||||
DescriptionCall the CSRPRFR cell pool service to return an allocated cell to a cell pool using the register interface, if your program cannot obtain storage for a parameter list. (The CSRPRFR1 service provides the same function with slightly enhanced performance.) EnvironmentThe requirements for the caller are:
Programming requirementsBefore you use cell pool services, you can optionally include the
CSRCPASM macro to generate cell pool services equate (EQU) statements.
CSRCPASM provides the following constants for use in your program:
RestrictionsNone. Input register informationBefore calling the CSRPRFR service, the caller must ensure that
the following access registers (ARs) and general purpose registers
(GPRs) contain the specified information:
Output register informationWhen control returns to the caller, the GPRs contain:
When control returns to the caller, the ARs contain:
Some callers depend on register contents remaining the same before and after issuing a service. If the system changes the contents of registers on which the caller depends, the caller must save them before issuing the service, and restore them after the system returns control. Performance implicationsNone. SyntaxWrite the call as shown on the syntax diagram.
ParametersABEND codesNone. Return and reason codesWhen the CSRPRFR service returns control to your program, GPR 15 contains one of the following return codes:
