Thank you to Raul and Oleg.
I employed Oleg's idea and because the result is
just a starting place for me to look more closely at the
results, I did not need to refine the search much to get a
useful result. I will show an excerpt of my saved session
below. I guess I am not too surprised I found so much "dead
wood" in my script with this approach.

NB. finddeadwood.ijs
NB. 3/29/8
NB. verb "search" below finds dead wood in a script
NB. used Oleg's hint: negative lookahead. See PCRE documentation.
NB. see "after" below for "(?!...)"
require 'files regex'
NB. the file must be both read and loaded
a =: fread jpath'~user/addons/turtle/tgsj3ogl.ijs'
load jpath'~user/addons/turtle/tgsj3ogl.ijs'
nna =: '(^|[^[:alnum:]_])'
nnz =: '($|[^[:alnum:]_])'
after =: nnz,'(?![[:space:]]*=[.:])'
search =: [{.~_*(nna,after,~[)(0&>)@[EMAIL PROTECTED]@rxmatch]
NB. b/c the script is in bmsturtle3 locale, it must be specified
(#~a:~:])(nl_bmsturtle3_ 1 2 3) search each <a
