RE: regex

Jorge,

Expanding on Karl's answer (and somewhat labouring his point) consider these examples:

$a =~ /Jorge/
$a =~ /^Jorge/
$a =~ /Jorge$/
$a =~ /^Jorge$/

This shows that regex providing four different capabilities:
- detect "Jorge" anywhere in the string
- detect "Jorge" at the start of a string (by adding ^)
- detect "Jorge" at the end of a string (by adding $)
- detect that the string is exactly "Jorge" (both ^ and $)

Replace "Jorge" with your pattern, and the result is the same.

Cheers,

Claude.
