IDA019R1

IDA019R1 is a CSECT within load module IDA019L1. It is the common record management request module. It verifies that a request is valid, and then tests the RPL for keyed or addressed processing. This includes sequential, skip-sequential, and direct processing of KSDS, ESDS and RRDS data sets. IDA019R1 then passes control to appropriate modules to perform the requested function.
