MVS requires DASD space for EREP’s temporary work data set whenever your input includes records on a history data set. You request this storage using the SPACE parameter on the DIRECTWK DD statement. Table 1 shows examples of coding for the SPACE parameter.

The amount of storage depends on the device type and the number of records to be processed. For the capacities of different types of DASD, refer to your DASD publications and your system’s hardware manuals.
