Using the SMS DATACLAS update utility with input from SYSUT1

Each record read from SYSUT1 must contain the complete set of data necessary for one operation on one DATACLAS. For example, to perform a GU operation followed by two GN operations, you would use the following.

   DATACLAS  NAME(ABC) RECFM(FB) LRECL(80) FUNC(GU)
   DATACLAS  FUNC(GN)
   DATACLAS  FUNC(GN)

The following is an example of JCL that uses SMS DATACLAS with SYSUT1.

//STEP20  EXEC PGM=MFCMD
//SYSUT1  DD DSN=TEST.CMDFILE,DISP=OLD
//SYSUT2  DD DSN=TEST.OUTPUT,DISP=OLD
//SYSPRINT DD SYSOUT=*
//SYSOUT   DD SYSOUT=*
