This exit is taken from HASPRDR in the JES2 main task. The exit occurs in the main processing loop of HASPRDR, after HASPRDR has read an entire JES2 control statement or JCL statement (including JCL continuations) but before it has processed any keywords on the statement. The statement may be outside a valid job (that is, when there is no current job structure active on the reader).

This exit is invoked for jobs submitted though card readers, RJE, SNA and BSC NJE, and SPOOL reload. It is not invoked for jobs submitted through the internal reader or TCP/IP NJE
