EVE$HELP.HLB  —  DCL
  DCL

  Executes a system command from within your editing session and puts the
  command output into the DCL buffer in a second EVE window.

  Example:

     The following command creates a subprocess for the DCL DIRECTORY
     command, to list the files with the type .TXT:

        Command: DCL DIRECTORY /NOHEAD /NOTRAIL /COLUMN=1 *.txt;*

  Usage notes:

  o  Output from the command (such as the directory listing) appears in the
     DCL buffer in a second window, like this:

     +--------------+
     |[] current    |     One window shows the buffer you are editing.
     |   buffer     |
     |--------------|     The other window shows the DCL buffer.  When the
     | DCL buffer   |     DCL command finishes, the cursor ([]) returns to
     |              |     your last position in the buffer in the other
     +--------------+     window.  The DCL window stays on the screen.

  o  To delete the DCL window, typically you use the ONE WINDOW command,
     which restores a single, large window, containing the current buffer.

  o  To put the cursor into the DCL window, use NEXT WINDOW. You can then
     edit the DCL buffer like any text buffer. For example, you can remove
     or copy a directory list and insert it in another buffer. See help on
     Windows.

  o  The DCL command creates a subprocess. Some commands apply only to that
     subprocess and do not affect the process in which you are running EVE.
     For example, the command DCL SET DEFAULT does not change your current,
     default directory for GET FILE, INCLUDE FILE, SAVE, or other commands
     in the editing session.

  o  In some cases, a DCL subprocess may continue even after the command is
     completed. Subsequent DCL commands may not work until you end the
     subprocess. For example, if you use the command DCL HELP to read a VMS
     help topic, then when you try to do another DCL command, such as DCL
     DIRECTORY, the subprocess is still running VMS HELP. In such cases, do
     the following:

        1.  Use the command DCL, letting EVE prompt for a command string.
        2.  At the prompt, press CTRL/V (or other key defined as QUOTE).
        3.  Press CTRL/Z (to end the subprocess).

     You can then do another DCL command, which creates a new subprocess.

  +----------------------------------------------------------------+
  | Do not use DCL to execute commands that generate continuous    |
  | output, or to run programs that do their own screen management |
  | or interact with the user such as MAIL.                        |
