How do I use "User Constants" for "Parameter Settings"?
Thank you Amel,
This allowed me to see that even though I couldn’t use it as a parameter value, the constant I defined was indeed saved to “mxconstants.h”:
- define DDS_IOUPDT_LENGTH 1000
However, since it’s defined as a #define I think it can’t really be a variable 
Best,
Cat
