Write Character Vector (3)
| Entry | |
|---|---|
| R0 | Character to write to active output streams |
| Exit | |
|---|---|
| R0 | Preserved |
Use
This vector is used to indirect all calls to OS_WriteC, and in turn OS_NewLine, OS_PrettyPrint, OS_Write0, OS_WriteI, OS_WriteN and OS_WriteS which call it.
Notes
In practice these SWIs may not actually call OS_WriteC or this vector if there is no reason to do so (i.e. the vector is not claimed, spooling and printer are inactive).
