DSNAME

Specifies the name of the library from which ZDT/CICS is to load the ZDT/CICS options module - usually HFM3POPT. Note that the member keyword can be used to specify an alternative name to HFM3POPT, if required.

If the DSNAME keyword is specified, ZDT/CICS bypasses the usual library search when loading the ZDT/CICS options module and only searches the specified library for the module.

When the DSNAME keyword is omitted, ZDT/CICS searches load libraries allocated to the user's session in the normal order, for example, LIBDEF, ISPLLIB, STEPLIB, JOBLIB, link list.

One use of this option is in an environment with stringent security requirements, where it is necessary to ensure that all ZDT/CICS users access a particular ZDT/CICS options module, and that the use of this option module cannot be avoided.

The DSNAME keyword is optional.
