the ? after the * is probably unnecessary, but I've gotten in the habbit of
it -- it makes a * or a + match a minimum number of characters necessary to
match the previous expression, as opposed to the default greedy result... In
this case it's probably just superfluous.

I'm not sure aobut PERL, but in CF ^ is only start of string if it's at the
beginning of the expression, so REFind("^...") will match the beginning of
the string ... Starting a character grouping with ^ like this [^0-9] the ^
becomes a "not" operator, so it's match all characters not in this group.

I wouldn't know, I don't really know much about PERL.
