Galil DMC-1800 Formatting Messages, MG STR S3, Using the MG Command to Configure Terminals

Text strings are specified in quotes and variable or array data is designated by the name of the variable or array. For example:

MG “The Final Value is”, RESULT

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 Gain of X is”, _GNX

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.
