UMACLIB
Specifies whether or not the user can override the data set specified in the MACLIB parameter, when a function is run in DLI mode. (When a function is run in BMP mode, irrespective of the setting of this parameter, the user cannot override the data set specified in the MACLIB parameter.)
Y
The user can override the MACLIB parameter.
N
The user cannot override the MACLIB parameter.
If you specify UMACLIB=N:
  • The IMS™ Macros Data set name field on the DLI Mode Data Sets 1 panel is protected.
  • MACLIB= statements in the HFMIMSIN input of batch jobs are ignored.
  • No MACLIB= statements are included in the JCL generated by ZDT/IMS dialogs.

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 Y (otherwise).
