WalkTree
                  Version 1.00:   April 19, 1986
                  Author: Don A. Williams


WalkTree is a small transient program that will  execute  another
specified program  at  every  level  of  the  Director  hierarchy
starting  with  the  current  directory.  This first release just
contains the basic mechanism  to  walk  the  directory  structure
recursively and to execute a program,  using MS-DOS function 4BH,
at every level of the hierarchy.  Future  releases  will  contain
the  ability  to execute a specified program on selected files of
every level of selected directories.

Usage:

WalkTree version 1.00 has a very simple command line:

    WT <any DOS command>

the angle brackets,  '<' and '>' are not  actually  part  of  the
command.  Any  command  or  program  recognized  by  DOS  can  be
specified  and  the  specified  program  will be executed at each
level of the  directory  hierarchy  beginning  with  the  current
directory on the current disk.


Examples:

    WT DEL *.BAK

    This  usage  of  WalkTree  would erase every .BAK file in the
    current directory and  every  directory  subordinate  to  the
    current directory.


    WT DIR

    This  usage of WalkTree would produce a Directory listing for
    the current directory and every directory subordinate to it.

   Version History

   Version 1.01 modified by John Covici March 12, 1987 fixed the following bugs:
   (1) assembles now with masm
   (2) Had to say [ds:2ch] rather than [2ch] to get indirection.  I
      think its a bug in the assembler.
   (3) Append cr to generated command line to prevent dos crashes.
