Hi everybody!

I've just started to learn ASM (finally got sick of basic) and obviously will have a number of questions to ask over the next month or so. Here's the first couple:

1. I displayed some text on the homescreen and I made the top line inverted (set textInverse, (iy+textflags)). After writing the inverted line I reset the flag. Everything looks fine until I call pgmio_exec. When I do that the top line gets reset to normal (uninverted) text. I did some experimenting and noticed that pgmio_exec will invert or uninvert the whole screen depending on the state of the textInverse flag. How do I stop this from happening?

2. What are the differences between: call_clrLCDFull, call_clrscrnfull, call_grbufclr.

Thank you in advance to anybody who answers my questions.

Matthew
