/* MARC - Archive merge utility
Version 5.21, created on 04/22/87 at 15:05:10
(C) COPYRIGHT 1985-87 by System Enhancement Associates; ALL RIGHTS RESERVED

Description:
This program is used to "merge" archives. That is, to move
files from one archive to another with no data conversion.
Please refer to the ARC source for a description of archives
and archive formats.
Instructions:
Run this program with no arguments for complete instructions.
Language:
Computer Innovations Optimizing C86
