   DESIRE COMMANDS AND PROGRAM ENTRY (terminate all entries with ENTER)

   Execute DESIRE commands by typing them, without a line number.
   To enter or modify a DESIRE program, you can

   1.  ENTER OR REPLACE NUMBERED PROGRAM LINES (as in BASIC).
       ERASE A LINE by typing its line number; erase multiple lines as in
       erase 12,15,30-75,90  .

   2.  Type /, and DESIRE will prompt you with AUTOMATICALLY GENERATED LINE
       NUMBERS starting at 210 and incrementing by 10.  If you enter a numbered
       line, line numbers will increment from your line-number value.  Change
       the line-number increment to n by typing  /auto n .  In auto-line-number
       mode, you can still enter commands by preceding them with / (e.g.
       /list).  To leave auto-line-number mode, type / .

   3.  After listing numbered lines with "list ...", type F10 or "ed" and use
       keypad keys to position the cursor; insert text or delete it with the delete
       and backspace keys.  Then F10 enters (only) the line with the cursor
       into your program.  ENTER enters a line and quits the editor.

   4.  TYPE F9 or "edit" TO ENTER OR EDIT YOUR PROGRAM WITH A TRUE SCREEN
       EDITOR.  The screen editor will return to DESIRE on exit (see help edit).
