Specifies the name of the PDSE program library in which ZDT/IMS stores the dynamic PSBs that it builds.

The DYNPSB parameter is used when PADS=Y is specified on the HFM1POPD macro statement.

If the IMS™ subsystem supports the use of dynamic PSBs in BMP mode, use of this library should be restricted to this subsystem.

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 HFM.DYN.PSBLIB (otherwise).

The user cannot override the value you specify for this parameter.

Note: When the PADS parameter is set to N, the dynamic PSBs that ZDT/IMS builds are stored in temporary data sets with system generated names.
