WDIR - Walk Directory

   This utility walks through a directory,  executing one or  more
commands on files matching a specified pattern. Its main use is to
provide  "wildcard"  capability to commands which do not  directly
support wildcards,  although it  can  be  quite  useful  in  other
situations as well.

   The format of the WDIR command is:

           WDIR <filespec> "command..." [options]

   The following options are available:

  +r      - Recurse into sub-directories. When this option
            is specified, WDIR will search sub-directories
            for matching files.

  -v      - Inhibit display of commands executed.

  +m      - Use multiple (wildcard) forms of commands.
            This options is used with '+r' to cause a
            single command to be executed once in all
            sub-directories that have matching files.

   The following characters have special significance when used as
part of the commands given to WDIR.

  @   - Substitutes the entire filename and extension
        (without directory) into the command.

  $   - Substitutes the filename only (without directory
        or extension) into the command.

  ^   - Substitutes the directory path (no filename or
        extension into the command.

  !   - Protect the next character in the command from
        the above translations.

   If none of the above characters are found in  a  command,  WDIR
will append the entire directory path,  filename and extension  to
the command.

   NOTE: WDIR accepts and executes multiple commands.

   Examples:

  WDIR *.c "del" +r           <=== One "DEL" for each FILE
  WDIR *.c "del" +r +m        <=== One "DEL" for each DIRECTORY
  WDIR \cmds\*.BAT "copy" "delete"
  (Copy all ".BAT" files from \cmds and then delete them)
