-- MACROSUB.ADA -- -- Grant of Unlimited Rights -- -- Under contracts F33600-87-D-0337, F33600-84-D-0280, MDA903-79-C-0687, -- F08630-91-C-0015, and DCA100-97-D-0025, the U.S. Government obtained -- unlimited rights in the software and documentation contained herein. -- Unlimited rights are defined in DFAR 252.227-7013(a)(19). By making -- this public release, the Government intends to confer upon all -- recipients unlimited rights equal to those held by the Government. -- These rights include rights to use, duplicate, release or disclose the -- released technical data and computer software in whole or in part, in -- any manner and for any purpose whatsoever, and to have or permit others -- to do so. -- -- DISCLAIMER -- -- ALL MATERIALS OR INFORMATION HEREIN RELEASED, MADE AVAILABLE OR -- DISCLOSED ARE AS IS.

IT IS USED TO REPLACE THE -- -- MACROS IN THE ACVC TEST SUITE WITH THEIR PROPER VALUES. THE -- -- STEPS LISTED BELOW SHOULD BE FOLLOWED TO ENSURE PROPER RUNNING -- -- OF THE MACROSUB PROGRAM: -- -- -- -- 1) Edit the file MACRO.DFS (included with the testtape) -- -- and insert your macro values. The macros which use -- -- the value of MAX_IN_LEN are calculated automatically -- -- and do not need to be entered. -- -- -- -- 2) Create a file called TSTTESTS.DAT which includes all -- -- of the .TST test file names and their directory -- -- specifications, if necessary. If a different name -- -- other than TSTTESTS.DAT is used, this name must be -- -- substituted in the MACROSUB.ADA file. -- -- -- -- 3) Compile and link MACROSUB. -- -- -- -- 4) Run the MACROSUB program. -- -- -- -- WHEN THE PROGRAM FINISHES RUNNING, THE MACROS WILL HAVE BEEN -- -- REPLACED WITH THE APPROPRIATE VALUES FROM MACRO.DFS. -- -- -- -- -- -- -- -- HISTORY: -- -- BCB 04/17/90 CHANGED MODE OF CALC_MAX_VALS TO OUT. CHANGED -- -- VALUE OF MAX_VAL_LENGTH FROM 512 TO 400. ADDED -- -- EXCEPTION HANDLER SO PROGRAM DOES NOT CRASH IF -- -- AN EXCEPTION IS RAISED. ADDED MESSAGES TO -- -- REPORT PROGRESS OF PROGRAM. CHANGED PROGRAM SO -- -- IT DOES NOT ABORT IF A FILE CANNOT BE FOUND. -- -- MODIFIED PROGRAM SO IT ACCEPTS FILENAMES WITH -- -- VERSION NUMBERS. -- ----------------------------------------------------------------------- WITH TEXT_IO; USE TEXT_IO; PACKAGE DEFS IS ----------------------------------------------------------------------- -- -- -- THIS PACKAGE IS USED BY MACROSUB.ADA, PARSEMAC.ADA, AND BY -- -- GETSUBS.ADA.
