I can go by the scr (screen mode) value and NumColors to know where the colors are set. Might as well use it before the BSAVE to hold the part of the bitmap for the PUT if needed. I can check the BMP depth to see if I need to do that.
I don't want to overload the memory in Qbasic as it does not seem to work as well as QB4.5. Some of my image programs will not BLOAD as well in QB1. However the programs ARE too big to compile in 4.5. Are you using QBasic1? I hope that can work also.
Well, I guess I have something more to play with LOL. And here I was getting ready to make a monochrome SAVER for Screen 2. I don't think there is a huge demand for it though. I also might try to convert 12 to 9, but those darn DAC settings are a pain.
