'cgl is a dispatch function for the 'cgi object. I got tired of
typing forward slashes :-)

Thanks! I'll check that out. In the meantime, I wrote a quick a dirty
help function:
cgi-to-hidden: func[v[block! string!] /local str val][
either string? v[
if not val: cgl[get value v][val: ""]
str: copy ml[input/type/name/value "hidden" (v) (val)]
][ str: copy ""
repeat name v[
if not val: cgl[get value name][val: ""]
append str ml[input/type/name/value "hidden" (name) (val)]
] ]
]
; and take note that cgl[get value name] <=> cgi/get/value name
; and for snippet of the calling code
form/action/method (cgl[get path thru "process"]) "POST"[
(cgi-to-hidden required-fields)
(cgi-to-hidden optional-fields)
; etc, etc, ....
<sigh>so much to do, so much to learn</sigh>
Thanks again Andrew.
