Lloyd,
        I never use the A, K, or E, B, C, conventions myself. I stick to
numbered pins. Many years ago (on another CAD package) I had seen some
problems and issues with alpha designated pins and just ran away from them
as fast as I could go. Today I set out a convention for diodes with pin 1 as
Cathode or Anode (depends on the CAD system and the company past history)
and go from there. Same for transistors. In a lot of cases I build special
diode or transistor symbols just to take care of the myriad of packaging
options. More symbols in the library to manage but it avoids some of the
stupid wrong symbol, wrong footprint problems with discrete semi devices.

        Your test engineer is from where? Nortel? Never heard of them, who
are they, what do they do? Are they one of those penny hi-tech stocks? 8^>
