Facilities for customizing the HFM1PARM definitions

You can use the HFM1PARM definitions to provide different options for ZDT/IMS users, based on the following environmental settings:

• The current z/OS® system ID
• The current version of ZDT/IMS
• The user's logonid

You can also split the HFM1PARM definitions across two or more members using the % (include) specification, and include comments using the * specification.

All of the facilities described in this section are optional. You do not need to use any of them.
