No actually. `/[^0-9]/` is correct, where `/\D/` isn't. Your perl is from the previous century if `/\D/` equals `/[^0-9]/`.	[reply] [d/l] [select]

No. `/\D/` is wrong. It will allow entries which Perl cannot convert to integers in a meaningful way. There are more that two hundred characters which aren't matched by `/\D/`, but for which Perl cannot do arithmetic.	[reply] [d/l] [select]
