#############################################################################
#
# File: filexref.icn
#
# Subject: Program to cross-reference files by components
#
# Author: David Gamey
#
# Date: July 7, 1994
#
#############################################################################
#
# This file is in the public domain.
#
############################################################################
#
# History:
#
# 11Jul94 - D.Gamey - Reorganized to eliminate empty columns
# 13Jul94 - D.Gamey - Added dateline & total number of files
# 29Jul94 - D.Gamey - Page numbers in headers
# 6Jan95 - D.Gamey - Allow DOS wild cards to select within directories
#
############################################################################
#
# Usage:
#
# dir dir1 /b /a:d > dirlist
# filexref < dirlist
#
# Note:
#
# Dir does not preface its results with the parent directory
# - take care!
#
# Options:
#
# -D Produce an ascii delimited file
# -h Exclude hidden files
# -n Page Length ... must be integer >= 25
#
#############################################################################
#
# Requires: MS-DOS compatible operating system
