                                   APPEND
          Locate files other than .COM .EXE .BAT by a search path
                              See also <PATH>

Locates files outside of current directory that have extensions other
than .COM, .EXE, and .BAT.

COMMAND TYPE: Internal and External     VERSION: 3.3 and up

USE:
(FIRST USE ONLY)
    APPEND [/X][/E]
or (to specify directories explicitly)
    APPEND d:path[;[d:]path ...]

(SUBSEQUENT USES)
     APPEND d:path[;[d:]path ...]
or (to delete appended paths)
     APPEND [;]
or (to modify action with certain commands - see below)
     APPEND [path] [/X:[OFF|ON]] [/path:[OFF|ON]]

d:path specifies the path to search. Paths cannot be specified the
   first time the APPEND command is loaded if either /X or /E are also
   specified.
;  to separate the APPEND paths or to request the list to be reset to
   null if the semi-colon is the only parameter.
/E is used to keep the APPEND paths in the DOS environment, similar to
   the <PATH> command.  APPEND searches the environment on each call to
   find the path. If the /E is not specified, the path string is held
   within the APPEND command.  The paths are not stored in the
   environment and can only be viewed or changed by using the APPEND
   command.
/X to process SEARCH FIRST, FIND FIRST, and EXEC functions.  Commands
   such as <COMP> and <DIR> use the SEARCH FIRST functions to search for
   files.  Commands such as <BACKUP>, <RESTORE>, and <TREE> use the FIND
   FIRST function to locate files.  DOS uses the EXEC function any
   time a command is entered.
   The following functions are processed by APPEND with or without /X:
   OPEN FILE, OPEN HANDLE, GET FILE SIZE

NOTE: If APPEND has been loaded with /X, before using BACKUP or
RESTORE, APPEND must be issued using null (;).

MSDOS 4.x  The extra parameters /x:off, /x:on are available to toggle
   the setting of this function.  Individual paths may be disabled or
   enabled from APPEND processing with the /path:on, /path:off
   parameters.

NOTE: /X and /E can only be specified on the first invocation of the
   APPEND command. APPEND must be used before <ASSIGN> if you intend to
   use the <ASSIGN> command.

The main use of APPEND is to allow applications to access auxiliary
files without needing run from the directory where those files are
stored. The command processor finds the application itself (.COM, .EXE
or .BAT) via the <PATH> command.  The APPEND paths then allow the
application to locate other files (such as dictionary or configuration
files).
