Using the IDCAMS LISTCAT Command

You can use the IDCAMS LISTCAT command to determine if SAM or VSAM data sets have associated DDM attributes and the value of the CCSID attribute. Figure 1 uses the LISTCAT command to generate a report on a data set named IBMUSER.DFMDATA:

Figure 1. LISTCAT Command

  //LISTCAT  JOB
  //STEP     EXEC PGM=IDCAMS
  //**************************************************************
  //* PURPOSE: LIST A CATALOG AND A CLUSTER
  //***************************************************************
  //SYSPRINT   DD   SYSOUT=*
  //AMSDUMP    DD   SYSOUT=*
  //SYSIN      DD   *
      LISTCAT LVL(IBMUSER.DFMDATA) ALL
   /*

Figure 2 shows the resulting output. The DDMEXIST field contains the value TEXT, indicating that associated DDM attributes exist. And the CCSID field contains the value X'01F4', NLS EBCDIC STANDARD.
