CSRREFR — Refresh an object z/OS MVS Programming: Assembler Services Reference ABE-HSP SA23-1369-00 |
||||||||||||||||||||||||||||||||||||||
DescriptionTo refresh changed data that is in a window, a scroll area, or
a temporary object, call the CSRREFR window service. CSRREFR refreshes
changed data within specified blocks as follows:
EnvironmentThe requirements for the caller are:
Programming requirementsNone. RestrictionsThe caller must follow all the restrictions imposed by the DIV macro. Input register informationBefore calling the CSRREFR service, the caller must ensure that
the following 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 access registers (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. You must code all parameters on the CALL statement in the order shown.
ParametersAll input to callable services is in the form of RX-type addresses. The parameters are explained as follows:
ABEND codesCSRREFR might abnormally terminate with abend code X'019D'. See z/OS MVS System Codes for an explanation and programmer responses. Return and reason codesWhen the CSRREFR service returns control to your program, GPR 15 (and return_code) contains a return code and GPR 0 (and reason_code) contains a reason code. The following table identifies return code and reason code combinations and explains their meanings. The data-in-virtual reason code, which is returned with CSRREFR return code X'C', is two bytes long and right justified. It is explained in the description of the DIV macro (DIV — Data-in-virtual).
