Writes a character to the currently selected output stream(s), expanding carriage return to a newline sequence.
Specification
| 6502 | Z80 | 6809 | PDP11 | 80x86 | 32016 | ARM | On entry: | On exit: |
| A | A | A | R0 | AL | R1 | R0 | = ASCII value of character to print | preserved |
Prints the character whose ASCII value is in A to the currently selected output stream(s) via OSWRCH. If A = &0D then OSASCI prints LF followed by CR.
Calling from BBC BASIC
- All normal BASIC output is via OSWRCH or WRCHV. 6502 BASIC outputs the "Bad Program" message via OSASCI.
