Just when I think I am beginning to understand this XML stuff, I hit another snag! After checking the SDK Parameters document I found an entry for "Transponder Code" and it stated to use "units bco16". The SDK Units document shows a "BCD16" and not a "bco16", so I think we have a typo. I have spent several hours, trying to find a code example, for programming a transponder and have failed. This is how I have interpeted it, from what I have read. To get the current transponder frequency to appear in my gauge window, this is part of the code that I have put together. What am I missing?%((A:Transponder1 Code,Frequency BCD16))%!d!Thanksgreenco

Hi,Try:%((A:TRANSPONDER1 CODE,enum))%!04d!Jan"Beatus Ille Procul Negotiis"

Thanks again Jan. This one is also going in my notes.greenco
