OI Control Statement

The OI control statement is used to turn on 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. The batch TMSCLEAN program is the only means of setting the scratch status. The format for the OI statement is:

OI FLAGx=value
