I have the Vassar spell checker (v2.2) installed and working from EVE with
no changes to the section files.

EVE looks for a file called SYS$SYSTEM:LNGSPLCOR.EXE , which is the main
image of DECspell, hence doesn't exist if you don't have it. If it doesn't
find it, it complains; if it does, it spawns the command
                "SPELL tempfile/OUTPUT=tempfile".

My method to get EVE to recognize the spell checker:

1. Create a file called SYS$SYSTEM:LNGSPLCOR.EXE. The contents are irrelevant.

2. Modify Vassar Spell's CLD to have a qualifier /OUTPUT.

     define verb SPELL
        image DECUS$:[EXE]SPELL
        parameter P1, label=FILES
        qualifier PERSONAL, label=PERSO, nonnegatable
        qualifier UPDATE, label=UPDAT, nonnegatable
        qualifier CHECK, nonnegatable
        qualifier LOGGING, label=LOGGI, nonnegatable
        qualifier OUTPUT, nonnegatable
           value (type=$outfile)

   The fact that the program never looks for and hence never uses the /OUTPUT
   is doesn't matter. EVE's invocation expects the output to overwrite the
   input which is what the Vassar SPELL program does anyway. This is just to
   keep the DCL parser happy!

3. Save the original (DEC) SPELL.CLD using VERB and replace in DCLTABLES
   with Vassar SPELL.

4. Tell users they can now use SPELL from EVE.

The reason I wanted to avoid changing the section file is that several users
have customized section files that it would be tedious for them to recreate
or for me to have to explain how to update the eve_spell() procedure!
