I'm fully aware of that, must I've never run into a use case, while I've had lots of cases where I wanted to fill an area with, e.g., X'00', X'40'.
If I ver run into a situation where I want to initialize to a repeating multibyte situation then MVC would be the way to go. I'm not saying it won't happen, or that others haven't run ino it. just that I haven't yet. -- Shmuel (Seymour J.)
