I think I read somewhere that is what keyed VSAM Index records are, aren't they? A count of equal key bytes and then the remaining non-equal bytes, followed by the RBA in the data component? Or is that a fib I was told?

Thanks! I did think of what CUSE would be perfect for: what I know as "vertical compression" but Google does not seem to know the term. Think of standard run length compression as "horizontal." Picture something like that, but where a code indicates "the next 'n' bytes of this record are identical to the bytes in the same position in the previous record." Only works for sequential files, because you need the previous record to decode this records. But works well where there are a lot of repeating fields. -- This message and any attachments are intended only for the use of the addressee and may contain information that is privileged and confidential.
