USER MANUAL Chapter 7 Application Programming • 135
The Final Value is 99999.99
The message command normally sends a carriage return and line feed following the statement. The
carriage return and the line feed may be suppressed by sending {N} at the end of the statement. This is
useful when a text string needs to surround a numeric value.
Example:
#A
JG 50000;BGX;ASX
MG "The Speed is", _TVX {F5.1} {N}
MG "counts/sec"
EN
When #A is executed, the above example will appear on the screen as:
The speed is 50000 counts/sec
Using the MG Command to Configure Terminals
The MG command can be used to configure a terminal. Any ASCII character can be sent by using the
format {^n} where n is any integer between 1 and 255.
Example:
MG {^07} {^255}
sends the ASCII characters represented by 7 and 255 to the bus.
