Answer / bhavani
When we retrieve data from a nullable field, we need to
have a null indicator declared in the working storage.
WS-NULL-INDICATOR s9(04) comp
And after you have fetched the value for that column,
we need to check the value of the null indicator.
It can have the following values
-2 - Exceptional condition
-1 - Null Value is present in that field
0 - Not null
