Data area description and format

Requests to EQQYCOM often involve either reading one or more records from an HCL Workload Automation for Z database or data set, or writing them. In both cases, the record is placed in a data area and its address provided in a fullword whose address is in the parameter list. When you are retrieving information, EQQYCOM places the required record in a data area and provides the address of this area. When you are writing information to an HCL Workload Automation for Z database or data set, your program must build its own data area and provide its address. Note that EQQYCOM might use the same piece of storage for data areas in successive data retrieval requests, overwriting the data area used for the previous request each time.
