Thank you very much! I just began learning regular expressions so I was avoiding it ^^;.	[reply]

It's hard to learn something by avoiding it!	[reply]

Though it's a good attempt, I'm not too impressed. If the requirements change from 1 letter to more, your code won't handle it. Your right hand side for the substitution is uglier than it should be. My proposed fix: `$combined =~ s/([a-z]+)(\d+)/\U$1:$2/i;` [download]	[reply] [d/l]

"If the requirements change from 1 letter to more, your code won't handle it. " If the requirements change from letters to kanji or hiragana characters, your code won't handle it either. And that is just as likely. Coding now to exceed the known requirements, in order to cater for some future, speculative change, is a waste of time and effort. When (if!) the requirements change, the the code can be changed to match the new requirements.	[reply]
