Yup! That did it.

However this is an idiom I'm not familiar with - I've only got the Camel's head here at work (Perl in a Nutshell) and the join entry doesn't expand on it. It's a great example of DWIM!

With my use of the explicit split, as I said, the split file had lines like:-

,XXXXXXXXX,,XXXXXXXXXX,,XXXXXXXXXX,,...

however, when I changed it to your use - even using my beginner's pattern of /(XXXXXXXXXX)/g - it DWIM'd!

If you (or another brother) have time I'd appreciate an "expanded" Perl baby-talk explanation - i.e. put in all the bits that aren't necessary so we can see what's been left out.

I (think I) understand the default $_ as being the input, but it's the use of a pattern to generate list context that's new to me.

Thanks in advance
