Retrieving an existing VSAM data set - with SMS

To retrieve an existing VSAM data set, code a DD statement in the form:
   //ddname DD  DSNAME=dsname,DISP=OLD
   //ddname DD  DSNAME=dsname,DISP=SHR

You can pass VSAM data sets within a job. (Note that the system replaces PASS with KEEP for old permanent VSAM data sets. When you refer to the data set later in the job, the system obtains data set information from the catalog.)
