NI Control Statement

The NI control statement is used to turn off bit values in FLAG1, FLAG2, FLAG3 or FLAG4. If the TM control statement is coded, the TM value must be verified in the flag field for the volume record to be updated by the OI or NI instructions. The scratch bit (X'04' in FLAG1) cannot be changed by this operation. If you desire the scratch bit to be reset use the UNEXPIRE keyword on the Volume Control Statement. The format for the NI statement is:

NI FLAGx=value
