Re: Range of numbers

No. [0-9] sets a set of characters, not numbers.

Do what you want with a regex is possible but, AFAIK cumbersome: /^(2[5-9]\d|[3-6]\d\d|7[0-2]\d|730)$/ should work (not tested)

Rule One: "Do not act incautiously when confronting a little bald wrinkly smiling man."

I wouldn't mix ranges with numbers and \d in a regexp, unless you know your perl is older than 5.6. Since the previous millennium, Perl has supported Unicode in some way or another. Which means that while `[0-9]` matches 10 characters, `\d` matches many more. Several hundreds of different characters in 5.10. Your suggested pattern, `/^(2[5-9]\d\|[3-6]\d\d\|7[0-2]\d\|730)$/` [download] matches `333`, `33۳` and `3۳3`, but not `۳33` (`۳` is Arabic 3).	[reply] [d/l] [select]

++ Thank you for the answer. I never thought that Unicode can be an issue in recognizing numbers. Rule One: "Do not act incautiously when confronting a little bald wrinkly smiling man."	[reply]
