This was a thread that has been taking place on Robelle-L, but a couple of messages slipped over here to HP3000-L. I'm sure that none of you have ever made an e-mail slip-of-the-fingers addressing mistake before :-). If you are interested in the Robelle mailing list, see the Web page: http://www.robelle.com/robelle-l.html or contact: [log in to unmask] for more details. We now return you to your regularly scheduled HP3000-L programming ... Cheers, David <[log in to unmask]>
