* CERN PROGLIB# Z044    INTRAC          .VERSION KERNIBM  2.11  850320
*
* CALLING SEQUENCE:     VALUE = INTRAC(DUMMY)
*               OR:     IF (INTRAC(DUMMY)) .....
*
* FUNCTION:     A LOGICAL*4 FUNCTION TO DETERMINE WHETHER A
*               PROGRAM IS RUNNING IN A TSO OR BATCH ENVIRONMENT.
*               THE FUNCTION HAS THE VALUE .TRUE. IF RUNNING IN A
*               TSO ENVIRONMENT OTHERWISE THE VALUE IS .FALSE.
*               THE ENVIRONMENT IS DETERMINED BY THE CONTENTS OF
*               ASCBTSB WHICH IS ASSUMED TO CONTAIN ZERO IF IN
*               BATCH AND NON-ZERO IF IN TSO.
*
* ARGUMENTS:     DUMMY  - A DUMMY ARGUMENT TO SATISFY THE COMPILER.
*                         THE ARGUMENT IS NOT CHANGED BY THE
*                         SUBPROGRAM REFERENCE.
