APPSEL - Selection section
This section identifies a particular field in an object. By specifying a field name and a comparison operator in APPSEL, you can limit the instances of the object that HCL Workload Automation for Z finds. APPSEL is pointed to by the APPOBJ_SEL_TRIPLET in its object section and must itself point to an APPVAL section where a selection value is specified. To identify one particular instance of an object, you might need to specify more than one APPSEL in the send buffer. The selection sections for a particular APPOBJ must be in contiguous storage.
If you do not specify APPSEL for a GET request, HCL Workload Automation for Z returns all instances of the object.
The selection section has this format:
