-- HISTORY:
--     RJW 08/25/87  CREATED ORIGINAL TEST.
--     DHH 03/30/89  CHANGED MOD 4 TO A MACRO VALUE AND CHANGED
--                   EXTENSION FROM '.DEP' TO '.TST'.

-- MACRO SUBSTITUTION:
--     $ALIGNMENT IS THE VALUE USED TO ALIGN A RECORD ON A BOUNDARY
--     DEFINED BY THE IMPLEMENTATION.
