On UNIX character-mode systems, when the terminal is under the control of ABL (in raw-mode terminal I/O), the messages appear at the bottom of the display. If the application previously set the terminal to cooked mode with a call to
proscopn( ), the messages are written to the current output destination. If the current output destination is the display, the messages appear on the display in normal video, similar to the output of the standard C library function
printf( ). For more information on raw- and cooked-mode terminal I/O in character mode, see
HostLanguage Call Interface.
