I am going through it by now.
But as I am not an IT-Guy, I unfortunately have my difficulties.
Set NullValue = 'NULL' ;
set NullInterpret ='0';
set NullDisplay ='<Null>';
set NullValue ='0';
What is the difference between these for expressions and which Expression works in the Script?
(I think only the third is working in my Script but I dont know for sure).
