WC (WINDOW_CLOSE) -- Close window and associated functions.
usage:  wc [-q | -f | -a | -s]


FORMAT

  WC [-Q | -F | -A | -S]


  The  WC  command  closes  (deletes)  a window.  It may also close the pad into
  which the window looks, depending on the following conditions.

  If other windows into the pad besides the  one  being  closed  exist,  the  DM
  naturally  leaves  the  pad open.  If there are no other windows into the pad,
  however, the DM closes it.  The closed pad is then either deleted (if  it  was
  temporary) or saved under its pathname (if it was named and permanent, i.e., a
  permanent disk file).

  If  the  pad  is  a  writable  edit  pad, and is being viewed only through the
  current window, the DM renames the old file by appending .BAK to its name, and
  writes the edited version to the original file name.  If multiple windows  are
  viewing  the  edit  pad,  WC simply closes the window -- it does not write the
  file or rename the old file.  To force the DM to write the file and create the
  .BAK version, use the DM command PW (PAD_WRITE) or the <EXIT> or  CTRL/Y  keys
  (see below).

  A  transcript  (output)  window  normally  cannot  be closed if it is the last
  window into an active process (see -F below).

  Note that the DM cannot delete a permanent pad (file); you must use the  Shell
  command DLF (DELETE_FILE) for this purpose.

  Two  keys  (or  control/key sequences) have been predefined to perform related
  functions:

                      KBD 2           KBD 1

  PW;WC -Q    (or)    <EXIT>  (R5)    CTRL/Y           Close window, pad;
                                                        update file

  WC -Q       (or)    <ABORT> (R5S)   CTRL/N           Close window, pad;
                                                        ignore changes


OPTIONS

  If no options are specified, WC closes the window and pad,  then  deletes  the
  pad (if temporary) or rewrites it (if permanent) as described above.  Only one
  of  the  following options may be specified at a time.  Auto-close is disabled
  by default.

  -Q                 Quit without updating pad (file).  Any changes  made  while
                     window  was  open are ignored.  The system prompts you with
                     "File modified. OK to quit?" if you have  made  changes  to
                     verify that you really wish to discard them.

  -F                  Force window closure, even if this window was the last one
                     open into a process.  Note that  the  process  will  become
                     inaccessible, however, if no windows are left.

  -A                  Enable  auto-close for current window.  When auto-close is
                     enabled, the current window will close when  the  pad  into
                     which it looks is closed.

  -S                  Disable  auto-close  for current window.  If auto-close is
                     disabled (the default condition), then the  current  window
                     persists after the pad into which it looks is closed.
