Notes If [[WrchV]] vector has not been intercepted with [[OS_Claim]] it will directly call the VDU driver which is faster, otherwise it calls [[OS_WriteC]] to write each character. An output stream can be specified by using [[OS_Byte 3]]. h4. See also * [[OS_Byte 3]] * [[OS_Claim]] * [[OS_WriteC]] * [[OS_WriteI]] * [[OS_WriteN]] * [[OS_WriteS]] * [[WrchV]]
