While you are at it, you should try to solve the type casting of some expressions... This should work:

Code:

Dim lsb, msb as uByte Dim address as uInteger ... address = lsb + (msb << 8)

But it doesn't, as it tries to shoft msb left 8 times but using 8 bits, so it always equals 0. You have to define msb as uInteger for it to work correctly.

In the same fashion:

Code:

Dim x, cx as uByte Dim dx uInteger ... dx = x - cx

dx is always positive, as x and cx are unsigned... But the results should be considered signed integer, and not unsigned char.

I find this to be the biggest problem with the compiler. No other language that I know behaves that way, and it forces you to find dirty walkarounds.
