This exit is taken from HASCINJR in the user environment. The exit occurs in input processing's main processing loop, after the entire JES2 control statement or JCL statement (including JCL continuations) has been read 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 through the internal reader or TCP/IP NJE. It is not invoked for jobs submitted through card readers, RJE, SNA and BSC NJE, and SPOOL reload.
