                                                                                                                     .
 number-of-bytes = number of characters to be written to another terminal

 format-statement-label = format statement containing the message to be written to the other terminal (may be a constant or
 variable)
                                                                                                                     .

Return:
If the write function is successful, the message contained in the format statement will be sent to the terminal specified.

If an exception occurs, byte 2 of the AX field will contain the DOS error code (in hex).
