Reasons for Dropping Control Fields If you are using an alternate collating sequence or opposite control fields you would probably drop the control fields. In each case the control information is so altered during the sorting process that it is of no use. You can, however, output those fields in a meaningful form by describing them twice; once as control fields and once as data fields. Since data fields are not involved in the sorting process, they are not changed by the program.
