sorry - if I've just sent a short message to this list instead of to Clyde Smith-Stubbs, I apologise. Also, thanks to Alan Nickerson :-) Like Alan, I can't contribute to this list - particularly when in the company of engineers of the calibre of the regular contributors. I'm still working on it, though :-) To me, this list is actually one of the benefits of working with PICs. regards, - Andy. ************************************************************* Andrew David Senior Project Engineer - Software Ultronics Division Andy@Ultronics.co.uk Ultra Hydraulics Ltd.
