  I am writing UDFs to do cases. I want to use UDF to obtain variables. But I do not find a similar UDF example in Help.
  How can I obtain more materials of predefined macros? For example, C_T is the temperature. How can I get all predefined macros and know the meaning of these macros.
  Is it possible to find such resources?

  Some are listed in the documentation, otherwise you may need to start digging in the header files.
