Thanks Bill, that's very helpful. Please let me see if I have this straight yet:
- If there is a format-8 DSCB, there will be a format-9 DSCB. - If there are > 3 extents (which are handled by the format-1) but < 133 extents, the format-9 record's DS9PTRDS will -> the first format-3 record. - For each 13 extents (after the first 3), an additional format-3 record will be created. The CCHHR of the n+1 format-3 record will be in the "n" format-3's DS3PTRDS. (Is it also in the "n" DS9F3 slot?) - There will not be an additional format-9 (subtype 1) record unless there are more than 10 format-3 records. If there are > 133 extents, the DS9PTRDS in the first format-9 record will point to the second format-9 record. Otherwise it will point to the first format-3 record? Thanks again!
