	ECHO.C
	Written by Leor Zolman, 3/82

	Gives display of computed command line, after WILDEXP has been
	applied. Can be used in conjunction with directed output to yield
	a file containing the disk directory for the current drive and user
	area, or just to check which files match a given wildcard pattern
	before using the wildcard in an actual command such as "cp".
