| CHROUT ($FFD2) | Programming/Assembly Reference/KERNAL
Write a byte to the output (default: screen).
Input: A = byte to write
LDA #$93 character code of SHIFT+HOME JSR $FFD2 clear the screen
LDA #$41 character code for letter "A" JSR $FFD2 print letter "A" on screen
On VC-20, C64, etc. writing text to the screen is often achieved by putting this call inside a loop. On C16/Plus4, that's not necessary, it can be done with a single call (see $FF4F). |
