The DOS 5.0 Undelete is better.  Who can remember the exact path and file name
of deleted files?  Not I!  Under DOS 5, all deleted files may be undeleted
until they have been overwritten, and you don't have to remember anything.  I
think I am going to do this TRASH directory hack.  Remember, under DOS 5, all
you have to know is "undelete *.*" and follow the prompts.  IBM could do better
on this count.
