Defining constants in formula node

[flaterp]

I apologize for the seemingly elementary level of this question, but nonetheless it continues to puzzle me. I am trying to enter several constants in a formula node and continually get the error message 'undefined variable' for the first defined. An example is shown below for the statement: 'CO = 192600;'

Error on line 1 is marked by a '#' character: "CO# = 192600;

I feel there is a problem with the way i am trying to define the constant (CO). Am I missing something? Since there are so many constants, I prefer to define the constants within the node instead of inputing on the border. Thanks in advance.

You need to use C syntax to declare the variable CO:
int CO;
CO=192600;

Alternatively, it is sufficient if you create an output terminal named CO in this case. No need to connect it, of course.
