Thank you for the confirmation as it wasn't entirely clear from the

Thank you ever so much, Kevin, for both the analysis / regex example, and
the reassurance that I was essentially on the right track with the approach
taken.
I'll be revisiting this issue later in the week when I have a larger time
block to devote to it [I suspect I'll be needing it !], and will no doubt
have more related queries.
In the mean time I've posted a number of miscellaneous, but simpler, Oz
queries: I certainly couln't let a regex-related problem get in the way of
my Oz explorations :) !
Cheers,
Anthony Borla
