Get a handler from a script

[Geoff Canyon]

Do you want them even though they are commented, or do you not want  
them?

For Navigator I don't care about commented handlers although I  
suppose maybe I should.

Since a comment relieves you of syntax requirements, this line is  
perfectly legitimate:

-- I've commented out this handler: on doSomething

I'm going to ignore such handlers, since they're just annoying. ;-)

That leaves two possibilities:

  -- on doSomething
  --on doSomething

So change the statement below to:

   if (word 1 of L is among the items of \
   "on,function,getprop,setprop,--on,--function,--getprop,--setprop"  
and...etc.) \
   or (word 1 of L is "--" and \
   word 2 of L is among the items of "on,function,getprop,setprop"  
and...etc.)

regards,

Geoff
