nextcode in CacheSQLStorage

[Steve]

I'm trying to map an existing global using CacheSQLStorage and only return
rows that have a number that is a multiple of 100 in subscript 3. I'm
guessing that I need to use nextcode in my CDL to start at 100 and increment
the value of the field/subscript by 100. Like this:



subscript 3 {

           nextcode = {

                        S {S3}={S3}+100

           }

            startvalue=100;

}

However, I get the error: #524: Invalid {Field} reference.



Any suggestions? I'm using Cache' 4.1.9.
