in reply to Question re numbers and strings

Clearly, Perl is trying to interpret as much of the string as a number as it can. For that reason, the following will also work:
my $field = 2; print "A number!", $field + 1 if ( $field > 1);
So despite the warning that $field is not numerical Perl does try to read the actual numerical value assigned.

Not sure if this is any help.
