Hi, all.
A few questions on the use of graphics in grx20. I am coming from Borlad Pascal, and have a lot to learn about graphics.
1) How do I flip back and forth between text and graphics screens? I know how to initialize the graphics, and the computer reverts to text mode when the progrma terminates. But I don't know how to flip between them myself.
2) How do I -- or can I? -- control the 0-15th entries in the palette? I have no trouble changing 16-255, but the bottom 16 seem resistant.
