Galil DMC-3425 Formatting Messages, Using the MG Command to Configure Terminals, MG STR S3

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;BGA;ASA

MG "The Speed is", _TVA {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.
