I/O operations
Reminder : N = [ABCD] with A=B=0 and N = 256*D + C, with cursor on C
What does Print means ? print ASCII char from code N. If N is greater than 255, we won't get into the complex Unicode stuff : let's just display N modulo 255 (C)
What does Read means ? read ASCII char from input. As it is always less or equal to 255, let's say the C part is read while the D part is equal to 0 (reset)
| Operation | 8-bit version | 16-bit version | Comments |
|---|---|---|---|
| Write | . | . | write C (D does not matter) |
| Read | , | ,>[-]< | read C and reset D |
