Is this sum function correct?

[Mirisage]

Hi SAS forum,

My "income" variable has missing values. I wanted to calcualte "Total" varaible by addiing 100 to "income" variable.

Based on literature, I speficied the below statement to deal with missing values.

Total = sum(of income, 100);

Could any expert tell me if my statement is correct?

Thanks

Miris
