I read the PIC list every day and am developing a PIC controlled ingestable coded fish tag for use in the DEEP sea. I have little experience of computer viruses and am prone to PANIC when my baby gets sick. Never the less I am now sorted in this department and apologise for upsetting the list with an only loosely related topic. I would take this opportunity to discourage any sarcasim and put downs which might make me cry and cause the keyboard to short. later, steve.
