Call defined property by UDF to another UDF
 

Hello
I am a new user of UDFs
My question is I defined a property (Saturation temperature depends on pressure) using a UDF code,
and I defined another UDF (source term UDF) which needs to include the property of the first UDF (Saturation temperature UDF), but the problem is how I can call the defined property from the first UDF(Saturation temperature UDF) and use it in the second UDF (source UDF)?

Thanks,
Mohammad
