(WC)
Mnemonic: (WC)
Hex equivalent: "@0E07@"
Discussion: The (WC) control code writes to the control line (a.k.a. "message line") of the controlling terminal. Subsequent data on the current write is displayed on the control line at the bottom of the screen display.
Typically, the control line is used to display special messages and/or warnings.
Note: The (WC) control code sends messages to the controlling device only, not to other terminals or devices. To send a message to another terminal, you must use the DOSRW function, explained in the DOS Function Calls section.
Example: a. 100 FORMAT (WC);"This is a message."
.
PRINT (0,100)
b. PRINT (0) (WC);"This is a message."
(Who Has File)

Discussion:
Example:
(Window Title Background)
Mnemonic: (Window Title Background=ARG1$,ARG2)
Hex equivalent: --
Discussion: This control code displays text on the top border line of the current Comet window.
ARG1$ is string (constant or variable) containing the text to be displayed in background characters on the top border line of the current Comet window.
ARG2 is a number (constant or variable) containing the horizontal starting position where the title text will be displayed (position 0 is the left-hand column).
Also see (Window Title Foreground).
Example: a. 100 FORMAT (Window Title Background="Title line",5)
.
PRINT (0,100)

(Window Title Foreground)
Mnemonic: (Window Title Foreground=ARG1$,ARG2)
Hex equivalent: --
Discussion: This control code displays text on the top border line of the current Comet window.
ARG1$ is string (constant or variable) containing the text to be displayed in foreground characters on the top border line of the current Comet window.
ARG2 is a number (constant or variable) containing the horizontal starting position where the title text will be displayed (position 0 is the left-hand column).
