To run flat file masking, JCL is supplied in the installation package as GTXMSKVS. This job uses procedure GTMSKVS.
If the output file you want to create has different DCB parameters to the input file you want to mask, you can uncomment the following line in the JCL file GTXMSKVS to override the input file's DCB parameters, with the appropriate values for your output file:
// *DEF1.DD03 DD DCB=(LRECL=XXX,BLKSIZE=XXXX,RECFM=XX)
In the PARMCD input for program GTXMSKF, in this job parameter VSAMLOOKUP should be set to Y.
Parameters to the JCL procedure are the same as for GTMSKF procedure, see Mask Files (Using Seedlists Stored in DB2), but in addition you should supply the following parameters:
  • GTSEEDDS
    The VSAM seedlist cluster name.
  • GTSUBDS
    The VSAM subset driving cluster name.
  • GTXREFDS
    The VSAM cross-reference cluster name.
