Bug? undeclared var, B4R error

[Mostez]

Hello,
I have an undeclared variable in my program, B4R did not report any errors and uploaded the sketch to Arduino Mega!

This is a warning, not an error.

Curious: Does the program nevertheless work as expected?

 

[Erel]

The program will work correctly. The compiler will treat it as a regular Int variable.

Thanks
