All-

1) Is there a quick way to any of several array fields are null?

Pseudo: If field[1] or field[2] or field[3] or field[4] or field[5] == ""
           do something
        end

2) Also, what's the programmatic way to bail from a program. Is it just a line that says "quit" or something? (In the present case, if any of the fields in #1 above are null, I want to stop the program.

Thanks!
