   PROBLEM DESCRIPTION:
     TSO/VTAM 3270 DATA STREAMS CANNOT BE TRACED BY GTF.
       WHEN ATTEMPTING TO DIAGNOSE PROBLEMS WITH TSO APPLICATIONS
       IT IS A USEFUL TECHNIQUE TO TRACE THE VTAM DATA TRAFFIC
       TO AND FROM THE TSO TERMINAL.  HOWEVER, TSO/VTAM SPECIFIES
       PROC=CONFTXT IN THE VTAM NIB WHICH INSTRUCTS VTAM TO TREAT
       TERMINAL TRAFFIC AS CONFIDENTIAL TEXT WHICH SHOULD NOT BE
       REPORTED BY A TRACE.  IBM HAS ADDED THE CONFTXT PARMLIB
       PARAMETER TO LATER VERSIONS OF VTAM SO THAT AN INSTALLATION
       CAN CONTROL THIS SETTING, BUT THIS FEATURE IS NOT SUPPORTED
       BY THE FREELY AVAILABLE VERSION OF TSO/VTAM.

       THIS USERMOD ADDS SUPPORT TO CORRECTLY PROCESS THE CONFTXT
       PARAMETER IN THE PARMLIB FILE OF THE TSO STARTED TASK,
       WHICH IS USUALLY A TSOKEY__ MEMBER OF SYS1.PARMLIB.
       FURTHER, TSO APPLICATION NIB INITIALISATION WILL ALTER THE
       NIB CONTENTS ACCORDING TO THE PARAMETER SETTING.  THE
       TCAST CONTROL BLOCK DSECT MACRO IS UPDATED TO REFLECT WHERE
       THIS SETTING IS STORED.

   SPECIAL CONDITIONS:
     ACTION:
       A "CLPA" MUST BE PERFORMED AT IPL TIME FOR THIS SYSMOD TO
       BECOME ACTIVE.
     DOC:
       CONFTXT=YES OR CONFTXT=NO CAN NOW BE SPECIFIED IN THE
       TSOKEY__ MEMBER OF SYS1.PARMLIB.  CONFTXT=YES IS THE DEFAULT.
       CONFTXT=YES WILL PREVENT THE TRACING OF TERMINAL DATA STREAMS.
       CONFTXT=NO WILL ALLOW THE TRACING OF TERMINAL DATA STREAMS.
