FILE_ALTERLIST_ Procedure
93 * Partition-volume names. A string containing the concatenated
names of all the secondary partition volumes, ordered by
partition number. You can add new names or change old
names; you cannot delete partition volume names. Each name
occupies exactly the number of characters specified in the
corresponding entry of item 92, hence the total length of this
item is the sum of the values in item 92. Partially qualified
volume names are resolved using the contents of the caller’s
=_DEFAULTS DEFINE. The volume name can be a full eight
characters (including the dollar sign) only if the system
(specified or implied) is the same as the system on which the
primary partition resides.
97 * Partition descriptors (32-bit). An array of 8-byte values, one for
each secondary partition. Each entry has the following
structure:
INT (32) priextentsize;
INT (32) secextentsize;
These values give the primary and secondary extent sizes in
pages. For Format 1 files, the size must be less than 65,535
pages. Format 2 is required for extent sizes over 65,535
pages. The length of this item in bytes is eight times item 90.
98 * Partition-volume relative names-length array. An array of INT
byte counts, each giving the length of the volume-relative name
(supplied in item 99) where the corresponding extra partition
resides. The length of this item is two times item 90.
