A test work station for testing ICs includes an output bench with sliding rails that partitions the table top of the output bench into segregated areas. A cross key including a plurality of pins is elastically held by an operating member holding mat including a plurality of holes into which the respective pins are insertable. The tracking code communicates with a referral system. The locking pin may be locked into a closed position by positioning the locking tab into a lock-out position. Such methods and systems replace a function name described in a header portion of a program module and a function name to be referred to by the program module with other names, and link functions having the same names as the replaced function names and executing the linked functions in place of an original function.
