# This library is no longer being maintained, and is included for backward
# compatibility with Perl 4 programs which may require it.
# This legacy library is deprecated and will be removed in a future
# release of perl.
#
# In particular, this should not be used as an example of modern Perl

;# Description:
;# This routine provides word completion.
;# (TAB) attempts word completion.
;# (^D) prints completion list.
;# (These may be changed by setting $Complete'complete, etc.)
;#
;# Diagnostics:
;# Bell when word completion fails.
;#
;# Dependencies:
;# The tty driver is put into raw mode.
;#
;# Bugs:
;#
;# Usage:
;# $input = &Complete('prompt_string', *completion_list);
;# or
;# $input = &Complete('prompt_string', @completion_list);
;#
