LSE$HELP.HLB  —  SPELL
  Syntax:  SPELL

  Runs DECspell on OpenVMS systems to check the currently selected text
  or the entire buffer for spelling errors.

  To run DECspell:

                1. Select the text you want to check. If you do not select
                   any text, SPELL checks the entire buffer.

                2. Enter the SPELL command. If you have less than a full
                   line, LSE extends the selected range to include the
                   beginning and end of the line containing the range.

  If the selected range (or the entire buffer) contains any overview
  records, a message informs you that the operation cannot be
  performed.

  LSE spawns a subprocess to run DECspell and writes out the current
  buffer or selected range to a temporary file in SYS$SCRATCH.  (The
  name of the temporary file uses the subprocess PID.) When SPELL
  finishes, LSE replaces the buffer or selected range with the new
  version of the temporary file (with corrections) and deletes any old
  versions of the temporary file.  You then resume editing.

  Do not use Ctrl/Y with SPELL.  Ctrl/Y deletes lines in the temporary
  output file, which destroys the selected range or current buffer.
