I stand edified. Had not seen the inverse, which I feel is kind of unusual. In general, when a field is governed by a length indicator, it seems that most often the length comes first. In this case, since the overall field itself is fixed, it doesn't much matter where you put the length. Maybe an EXecute MVC or CLC is a tad simpler if the thing being handled comes first. In any case, finding room for an 8th meaningful character is going to be a massive undertaking. Besides OA51203 (which looks like Omegamon), there are going to be a ton of supporting APARs.

Even the structure of UADS for a user is set of multiple members named as userid+digit, which requires an id of 7 characters or less." Uh no. In a couple of major TSO cblocks, it's a 7 character field FOLLOWED by the length field...
