***       SENSE SWITCH OPTIONS.
*
*         THE FOLLOWING OPTIONS ARE SELECTED IF THE CORRESPONDING
*         SENSE SWITCH IS SET *ON*.
*
*         SSW1   RETAIN USERS IN EJT (DETACHED) IF IAFEX IS IDLED OR
*                ABORTS.  THIS WILL RETAIN USERS ACROSS A RECOVERY
*                DEADSTART.
*
*         SSW2   DO NOT RELOAD AFTER AN ABORT.  RELEASE OUTPUT FILE TO
*                THE OUTPUT QUEUE.
*
*         SSW3   ABORT ON ABNORMAL CONDITIONS.  THIS WILL FORCE AN
*                INTERNALLY GENERATED ABORT WHEN AN INTERNAL ERROR
*                SITUATION OCCURS.  A DAYFILE MESSAGE WILL BE ISSUED
*                GIVING THE NAME OF THE SUBROUTINE BY WHICH THE ERROR
*                WAS DETECTED.
*
*         SSW4   DUMP FIELD LENGTH TO THE OUTPUT FILE AFTER OPERATOR
*                IDLE.
*
*         SSW5   DUMP FIELD LENGTH TO THE OUTPUT FILE AFTER AN
*                INTERNAL ABORT ON ABNORMAL CONDITIONS.  THE OUTPUT
*                FILE WILL NOT BE RELEASED TO THE OUTPUT QUEUE UNTIL
*                AFTER IAFEX TERMINATION UNLESS SENSE SWITCH 6 IS SET.
*                THIS SWITCH IS SET AUTOMATICALLY DURING INITIALIZA-
*                TION AND SHOULD BE CLEARED VIA AN *OFFSW* WHILE IAF
*                IS RUNNING IF THIS OPTION IS NOT DESIRED.
*
*         SSW6   RELEASE THE DUMP OUTPUT FILE TO THE OUTPUT QUEUE
*                IMMEDIATELY AFTER A IDLE OR AN ABORT.
