Last weekend I thought it would be nice to display the ident of the nav radios currently selected, so I went through the A variables and found NAV1 Ident, NAV2 Ident and ADF1 Ident. However these did not appear on screen as I expected. I've since spent some time delving into .CAB files, and I've finally got it to work using - <string>%NAV1 %((A:NAV1 Ident, string))%!s!%</String> What I don't understand is what the !s! does - all I know is that it works with it, and without it it doesn't. Any ideas? Frank T.
