Console I/O Functions
The IN and OUT MPL functions may be used to perform console I/O.

The OUT function writes a specified text string to the console. The OUT function is expanded as a null string. The syntax for the OUT function is:
%OUT (Enter Baud Rate) %SET (BAUD_RATE,%IN) BAUD_RATE = %BAUD_RATE
Enter Baud Rate>>
BAUD_RATE = 19200
