DFSVSAMP
Specifies the name of the data set that contains the parameters defining the IMS™ buffer sub pools for VSAM and OSAM data sets. When a ZDT/IMS function is run in DLI mode, the specified data set is allocated to the DFSVSAMP DD.

If the specified data set is a PDS or PDSE, specify the required member name of this data set in the VSMPMEM parameter.

This parameter is optional. If it is not specified on the HFM1POPI macro statement, ZDT/IMS uses either the value specified on the HFM1POPD macro statement (if specified on that statement), or IMS.PROCLIB.

If you do not want the user to override the value you specify for this parameter, set UDFSVSMP=N.
