   PROBLEM DESCRIPTION:
     STAX MACROS FROM LATER MVS VERSIONS CAUSE ABENDS UNDER MVS/370.
       WHEN PROGRAMS WITH STAX MACROS ASSEMBLED WITH MACLIB FROM
       MVS/XA OR LATER WITHOUT SPLEVEL SET TO 1 RUN ON MVS/370,
       THE SVC PARAMETER LIST HAS A DIFFERENT FORMAT WHICH IS NOT
       CORRECTLY PROCESSED, AND WHICH CAN CAUSE ABENDS SUCH AS
       S0C4.

       THIS USERMOD CHANGES THE STAX SVC SERVICE ROUTINE TO CHECK
       FOR A FORMAT 1 STAX PARAMETER LIST DURING PARAMETER VALIDITY
       TESTING AND WHEN THE PARAMETER LIST IS COPIED FOR PROCESSING.

   SPECIAL CONDITIONS:
     ACTION:
       A "CLPA" MUST BE PERFORMED AT IPL TIME FOR THIS SYSMOD TO
       BECOME ACTIVE.
