I've kept playing with it. I realized that using the perl scanner,
instead of the text one, for R files (this can be done via the
language map file) gives much more reasonable output. So the last
copule of evenings I've been looking at the scanner code and, using
the perl one as a basis, I've been hacking one for R. It seems to work
reasonably well. I'll let the list now when its done (I expect no
more than a week).
I haven't written a line of SAS in the last 8 years, but a quick
solution could be to use the perl scanner and modify, if needed, which
are chacaters of tokens and which are delimiters.
