PREPCHECK

a procedure originally developed in early 1962 as a way of cleaning up a case in order to run 3D Criss Cross. Its purpose was to get around an auditor's difficulty in "varying the question" in pulling withholds (later referred to as Prepchecking by the Withhold System). In July 1962 it was further developed and began being done by repetitive command. —HSSC Glossary (approved 3-9-90)
