Norm,
?
DecoderPro actually has 2 different sets of Import/Export operations. The main screen's File menu is not what you want.
?
Open an individual roster entry, and use that File menu's commands for Import/Export. CSV is an option there. That will give you all of the CVs for that loco.
?
I've written my own Access app to read in all of my exported locos' CV data, one loco at a time. My app can also export a CV file which DecoderPro's import command on the individual roster entry's menu can import. I had to work around a bug in DecoderPro Ver.4.26+R381c8dfc32 code to do it. I'm not sure which later version fixed that bug.
?
Feel free to PM me if you want to discuss further.
