Please read the OP and the variable names in the test code before slapping hands. You can be right from your implied point of view, but I had my rationale when posting (which implies that I tested my code, of course)
Here, I'm considering digits as a character class, not as components of a number whose semantic is different from that of a string; this is why I name my variable $start_digits, not $num as you do. As you've surely noted, the OP never talks about numbers, always about digits (anyway, as I noted in my post, the OP was not clear about the usage of this extracted data). Thus, when I thought about putting "*" or "+"*, I considered that if there were no digits it was good, and the returned string would be empty. I think you can agree with me that, had the OP asked for initial letters, the regex: would do the job. *I swear I thought about that! Flavio (perl -e 'print(scalar(reverse("\nti.xittelop\@oivalf")))') Don't fool yourself.In reply to Re^3: what is the best way to seperate the digits and strings from variable ?
