Ok thank you.

Sorry I misunderstood, the DCS-BIOS version is 0.7.49. I repeat, the problem is not DCS-BIOS but the ARDUINO ide which, as is obvious, does not allow the use of mathematical signs in the name of functions, DCS-BIOS has nothing to do with it. Anyway I solved, as you said, by replacing the (-) with (_), I thought they were references to proprietary functions of dcs-bios but this was not the case. Thank you.

Thanks for the reply, I'm using the latest version of DCS World Openbeta, it updates automatically. I tried to replace as you advised me and it works, I thought those calls were to functions written like that. Thank you very much

I'm creating a display to show the active frequency on the A4, but unfortunately the code to be entered is wrong, the separator lines (-) are not recognized by arduino ide. void onArc51-freq-xxxxxChange(unsigned int newValue) { /* your code here */ } DcsBios::IntegerBuffer arc51-freq-xxxxxBuffer(0x84c6, 0xffff, 0, onArc51-freq-xxxxxChange); does anyone know how to help me ?
