You can code exactly like that in Perl, thanks
to the
/x modifier. It allows you to
insert comments inside the regexp.
$callerid =~ / # we want to match
( # and remember
. # any character
{7} # 7 times
) # stop remembering
$ # then the end of line
/x; # and that's the end of the match
In this particular case, this is overkill, but in
some cases, it can be very useful in more cmoplicated
situations.
And as all others in this thread have said, I too
recommend using substr.
