10.2.1 General Exits

This section provides a description of the general exits that
are shared by TSO with the other installed CA MICS products.

Each exit description includes the name and title, a
description of its purpose, when it is invoked, and whether
or not it has an interface to the CA MICS Accounting and
Chargeback Product.  It also shows which data elements are
available, the special considerations to note, and a sample
user exit.

| _ U S R S E L |  Input Record Selection Exit (_USRSEL)
+---------------+

DESCRIPTION:
The _USRSEL exit provides the ability to select records that
may be processed by the TSO input format routine.  It is
similarly invoked to provide data selection for each CA MICS
component.

INVOCATION:
The  _USRSEL exit gains control during the input format phase
of the TSO daily update process step (DAY010).  It is invoked
after the account data SYSID header and other common fields
have been read, but before the front end record processing.
See Chapter 9 of this guide for more information.

ACCOUNTING INTERFACE:
No interface is provided.

USES:
This exit may be used to exclude records from processing
based on their source, type, or origin.

ELEMENTS AVAILABLE:
This exit is referenced by many different CA MICS products.
To help identify the caller, the ROUTINE variable is
initialized with the module name.

The element SKIP_REC is initialized to zero just prior to the
exit.  If the exit code sets SKIP_REC to one, that record
will be bypassed.

CODING RESTRICTIONS:  Refer to the System Modification Guide,
