READONLY
Specifies whether or not the IMS™ subsystem is to be defined as Read Only.

When an IMS subsystem is defined read-only, only the ZDT/IMS non-update functions, that is, Browse, Batch Browse, Extract and Print, can be run against databases in the IMS subsystem; ZDT/IMS prevents the user running the update functions, that is, Edit, Batch Edit, Load, Initialize and Delete/Define.

N
The IMS subsystem is not to be defined as Read Only.
Y
The IMS subsystem is to be defined as Read Only.

When you specify two values in parentheses, separated by a comma, the first value is used for BMP mode and the second value is used for DLI mode. When you specify a single value, this is used for both BMP and DLI modes.

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 "(N,N)" (otherwise).

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