gtps1m2a | System Macros |
Use this system macro to provide an interface between cycle down routines in CVCW and cycle down subroutines that reside in the control program (CP).
Format
|
The parameter is required for the CLES function and is otherwise ignored.
When FUNCTION=CLES, a value of zero indicates that no ECBs for the calling ECB subsystem were found on the requested dispatch list which satisfied the remaining selection criteria. A value of one indicates that at least one such ECB was found.
When FUNCTION=ETES, the parameter is ignored.
When FUNCTION=ETCT, the value returned is the count of non-system ECB in the subsystem.
Entry Requirements
The register specified by the LIST= parameter must contain a CLH List value as noted above (for the CLES function only).
Return Conditions
