According to the Firebird Language Reference[1], the
RDB$RELATION_FIELDS.RDB$UPDATE_FLAG signals whether a column is a
computed column (0) or a regular column (1) (or I guess, updatable (1)
vs not-updatable (0)). In practice, this doesn't seem to be the case

Updatable vs non-updatable is correct.
Hi *,
I'm missing something obvious, probably because I was looking at these bytes
for too long. I constructed this SPB:
2, 2, 116, 3, 0, 0, 0, 83, 114, 112, 111, 0, 1, 0, 0, 68, 55, 57, 67, 56, 51,
52, 70, 66, 65, 49, 54, 67, 50, 54, 69, 50, 56, 53, 65, 67, 57, 69, 57, 50, 48,
57, 68, 65, 57,

right? What am I missing?

Aha! I suppose in version 2 I can't send data with 2-byte length, right?

Aka, I need to jump to version 3 and use 4-byte length.

Exactly.
V.3 for SPB is like v.2 for DPB.

Thanks. Now I see the 2-byte length is only used for i.e. isc_info_svc_line.

BTW, anybody remembers the reason why version 2 has two values -
isc_spb_version, isc_spb_current_version - at the beginning?

Sooner of all this should be asked in Borland / Inprise - that was so in
IB6.0.

No obvious explanation but its the best you will get

Interesting:
"An example buffer adheres to the following format: isc_spb_version
isc_spb_current_version This will allow the addition of spb versions without
the need to renumber or add additional flags for buffer versioning."
