>Hi,
> I have declare a public variable PUBLIC RxDATA in myclass.INIT. This variable will be used by a anywhere in myclass. It works fine at first. When I tried to subclass it become mysubclass, VFP give me error RxData is not found. I am suprise that why it happen? Therefore, I declare PUBLIC RxData in main.prg and it doesn't work too except I declare it in mysubclass.init again. Why ? What have I do wrong?

It is better to avoid public variables if possible. Why don't you describe what you are trying to do.
