Specifies the number of additional page-fixed buffers to be made available to a Fast Path region if the normal allotment (specified or defaulted in IMSNBA) is used. The number specified is used by ZDT/IMS functions when they access Fast Path databases.

The number you specify must be in the range 1 to 9999.

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 6 (otherwise).

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