Hi danambroseUK,

What I think you want to do is replace all of the number strings in a single, global regular expression substitute.

You could do this with, for example: 

$mystring =~ s/(\d{3,5})/<b><a href='lookup.cgi?id=$1<\/a>/g;

Several things to note:  1) you can change the \d{3,5} if it turns out you have numeric strings which are less than 3 or greater than 5 digits.  2) you need to escape the '/' in <\/a>, since it would improperly terminate the regex otherwise.  3) the expression $1 is a backreference, used to specify the thing that was matched.

s''(q.S:$/9=(T1';s;(..)(..);$..=substr+crypt($1,$2),2,3;eg;print$..$/
