Thanks for the information. Since I'm using sdcc,I updated it to use C:

Just looking at your code, I see you are only setting a few registers for displayed characters wide x high.
I would recommend setting all of the registers in the table previously provided so that you are not relying on
the previous screen mode having the correct sync width, display start address etc.

Also, you can actually turn off the cursor without putting into an off screen area. I'm not sure what putting it into an off screen
address would do to be honest. If you set bit 5 of the cursor start scan line register (R10) this turns off the cursor.
