DL.EXE is a directory lister program that supplements "dir".
The list of files is stored as a sorted doubly linked list.
The search features of FlexList are used to find a file as
you type its prefix letters. The ascii view of a file is
implemented using a doubly linked list of file subpage
positions. I think you'll find DL.EXE a useful utility to
have around to clean up directories. Some useful additions
would be a view of two directories at a time and a view of
the directory tree with cd navigation. It would also be
nice to have the ascii and hex viewers be editors.
