If any records have been added, the EOD is updated asappropriate. Any functions specified in the operand fields <strong>of</strong> the CLOZ instructionare performed. When the CLOZ is completed, the op code in the lOB is reset to O.For an erase type data set, the block length, record length, and EOD are updated onthe HD R 1 label to the values in the lOB.Object Code Instruction Format 173
