Greg, did this ever get answered? I'm trying to catch up on my email and didn't
see a response to this followup. My guess would be because the first instance is
only matching once, so your getting the pos of the first (and only current)
match. Since you used the c modifier you should be able to use that regex again
with the /G (?) anchor in the pattern to have it start at the last match.
The second case the regexp is called in list context, so makes all the possible
matches. There is no pos afterwards because the last case didn't match - the /g
was done.
At least that's my guess. However, that might not be the end of this. Look into
the @- and @+ arrays, which I think (no docs handy) will do what your looking
for. HTH!
