Interestingly enough, it is for PI/open but not for UniVerse. The reason why this works is because in both PI/open and UniVerse the @n variables persist between successive evaluations of I-types. In PI/open, they are in a common block. I haven't studied the mechanism in UniVerse.

Is the ;@ required? How does this work? I used to using @1 in I descriptors to reference the first value, but how does this reference the previous value?
