Nick -
I think -syntax anything- may actually achieve what I want inside an .ado
file as you suggest. I was not aware of the "anything" argument. It
apparently is not in the manual (at least I can't find it) - but it does
appear in the -help-. I see a whole new vista of possibilities now that I
know about this trick. Thanks for the suggestion.

I assume you mean to say "ado-file", not "do-file".
My approach, if you want the if/in and/or options parsing capability of
syntax, would be to use the "anything" argument of -syntax-, which
allows an arbitrary set of stuff where the varlist would normally go.
syntax anything [if] [in] , OPtion(string)
See -help syntax-
