Defining the internal reader facility

In JES2, define the attributes of the internal reader facility with the INTRDR statement.

There are three types of internal readers:

TSO logons are submitted by use of TSOINRDR. TSUINRDR and TSOINRDR are used interchangeably.
Started tasks are submitted by use of STCINRDR.
Batch jobs are submitted by use of INTRDR.

In JES3, internal readers are dynamically managed by the JES3 global and are always available for use.

If BATCH=NO is specified, you cannot use internal readers for batch jobs. However, you can still submit batch jobs through real (local) card readers, RJE, NJE, or spool offload.
