How do I fix this error: ERROR 159-185: Null parameters for DIVIDE are invalid.

This is SAS log excerpt:

Give &RNSONFA a value that.

I recommend considering using the function STRIP to reduce the number of parantheses involved. You find a lot of code with trim(left(<value>)) because a long time ago there was no single function to do that. Strip was introduced as an alternative to trim(left because we used that so frequently.

[Kurt_Bremser]

You do

%LET RNSONFA = ;

That causes the macro variable RNSONFA to be empty.

When you do

divide(Total_n,&RNSONFA.)

this resolves (after macro expansion/interpretation) to

divide(Total_n, )

which is invalid.

I inherited this program from a programmer that left the company 3 months ago.  This report has been running on scheduler since then, without error.  Why is something that has been working all along, now causing an error ?

[Kurt_Bremser]

To really determine that, one would need a holistic view.

Complete code, everything concerning the scheduling, code of the system batch scripts, etc

Take a look at the revision history.

Something has changed, or the problem would have been there from the beginning.
