"Nutty quip goes here!"

=> R0 = character to write to active output streams
<= R0 preserved

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. 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).

See PRM 1, page 80.
