Ah you're right, I didn't read the message properly. It's an error *in* Low.pm, not Low.pm itself. Thanks for that.

It's true that I'm not very experienced at installing from CPAN. I use ppm when I can, but this isn't on it. I did try

Makefile.PL
nmake
nmake test
nmake install
[download]

but it failed several times. I emailed the auther about it's failure to install, he was very helpful but mainly a Linux guy and could only say that he know a lot of windows installers had had problems. So I thought a cut and paste job might work. Clearly not. Maybe I'll go back to the install and paste the issues here and then everyone can benefit from it.

Thanks and regards

Steve
