In addition to variables, functions and commands, responses can be used in the message
command. For example:
MG "Analog input is", @AN[1]
MG "The Value of KDX is ", _KDX
Formatting Messages
String variables can be formatted using the specifier, {Sn} where n is the number of characters, 1
thru 6. For example:
MG STR {S3}
This statement returns 3 characters of the string variable named STR.
Numeric data may be formatted using the {Fn.m} expression following the completed MG
statement. {$n.m} formats data in HEX instead of decimal. The actual numerical value will be
formatted with n characters to the left of the decimal and m characters to the right of the decimal.
Leading zeros will be used to display specified format.
For example::
MG "The Final Value is", RESULT {F5.2}
If the value of the variable RESULT is equal to 4.1, this statement returns the following:
The Final Value is 00004.10
If the value of the variable RESULT is equal to 999999.999, the above message statement returns
the following:
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.
