|||||||||||||||||||||||||||||||||||||||||||||||
REQUEST=QUERYDYN allows you to query whether the ADD and DELETE functions are available. EnvironmentThe requirements for the caller are:
Programming requirementsThe caller must include the CSVLPRET macro to get equates for the information returned via the DYNFUNC parameter. RestrictionsThe caller must not have functional recovery routines (FRRs) established. Input register informationBefore issuing the CSVDYLPA macro, the caller does not need to place any information into any general purpose register (GPR) or access register (AR) unless using it in register notation for a particular parameter, or using it as a base register. 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. SyntaxThe CSVDYLPA macro is written as follows:
ParametersThe parameters are explained as follows:
ABEND codesNone. Return codesNone. ExamplesNone. |
