Charles, As usual, I've already exceeded the limits of my practical knowledge of null support. As I said, I generally prefer to use the coalesce function, which eliminates the null issue. I haven't had a need to learn more about null support....

I was under the impression that this keyword affects only RPG native processing. Since the original poster was using embedded SQL, he needed to include a manually defined NULL indicator array. If ALWNULL(*USRCTL) was specified does RPG automatically track and pass the NULL indicators?
