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;BGA;ASA
MG "The Speed is", _TVA {F5.0} {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.
