Peter,

I also want to mention here that user errors and warnings can use the value of variables to make them more informative.  Try cutting and pasting the code below into the SxKey IDE and assembling it.  By un-commenting the different defintions for "ThisNodeVar", you can see how the user message can tell you what the value of "ThisNodeVar" is.  I often use this in my code for reminding me of things like baud rate or address settings in my projects.
