   PROBLEM DESCRIPTION:
     THE &SYSUID SYSTEM SYMBOL IS NOT RESOLVED IN SUBMITTED JCL.
       THE &SYSUID SYSTEM SYMBOL CAN BE VERY USEFUL IN REDUCING
       THE CUSTOMIZATION THAT SHIPPED SAMPLE JCL REQUIRES BEFORE
       BEING SUBMITTED, BUT THIS IS NOT SUPPORTED BY MVS 3.8.
     JOBS SUBMITTED BY TSO USERS DO NOT INHERIT THE USER ID.
       USER= AND PASSWORD= MUST MANUALLY BE SUPPLIED BY A TSO USER
       SUBMITTING BATCH JOBS FOR THE JOBS TO RUN WITH THE USER'S
       SECURITY PROFILE, WHICH INCREASES THE RISK THAT THE SECRECY
       OF THE USER'S PASSWORD CAN BECOME COMPROMISED.

       THIS USERMOD SHIPS A VERSION OF THE IKJEFF10 EXIT FOR THE
       TSO SUBMIT COMMAND WHICH APPENDS THE USER AND PASSWORD
       PARAMETERS TO THE JOB JCL STATEMENT IF NOT ALREADY ADDED
       IN AN ENVIRONMENT WHERE A SECURITY PRODUCT IS ACTIVE.
       THIS EXIT HAS BEEN ENHANCED TO RESOLVE THE &SYSUID SYSTEM
       SYMBOL (WITH TRAILING PERIOD IF PRESENT) WHEN FOUND IN THE
       OPERANDS (MEANING NOT IN LABELS OR VERBS) OF THE FOLLOWING
       TYPES OF JCL STATEMENT:

         - JOB
         - DD
         - COMMENT
         - COMMAND

       THE FOLLOWING TYPES OF JCL STATEMENT ARE IGNORED BY THIS EXIT:
         - EXEC
         - JES2 JECL
         - NULL

       NOTE THAT &&SYSUID WILL BE LEFT UNALTERED.

       &SYSUID RESOLUTION DOES NOT REQUIRE AN ACTIVE SECURITY PRODUCT.

   SPECIAL CONDITIONS:
     NONE.
