Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me.

Forum Index : Microcontroller and PC projects : RGB(..) does not return correct value

Cl has to be an integer to fit the resulting number into it.
variables default to floating point unless specified otherwise

CLS
dim Cl as integer
Cl = RGB(255,255,255)

Print Hex$(Cl),Hex$(RGB(255,255,255))

Line 25,25,100,100,1,RGB(255,255,255)

Line 50,25,100,100,1,Cl

Thanks Jim,

Another case I knew the answer would be simple. I will have to get into the habit of declaring a variables type.
