Fabio is your question:
----
[no] why is APPEND MEMO not on that list of commands

It is a issue on VFP9b doc; i send this for a complete fixing on VFP9 doc.
Same issue occur for SCATTER, GATHER ...
----

I'm not sure why you said "no" <g>. I think you're requesting that the docs be clarified to include all possible commands that would work for a blob as well as a memo field here. I would agree with that request. But, see below... it might be better to have a list of commands that impact memo fields that do *not* impact blobs...

-----
[no] in what scenario is APPEND MEMO useful with a blob?

The scenario is the same of a memo field.
-----

I would disagree *slightly* with you here; I can't imagine a case where the ADDITIVE keyword for APPEND MEMO would make a lot of sense for blobs although it is obviously quite useful for memo fields <s>.


-----
[yes] something else?


MEMO commands clause == (memo or blog fields) on all VFP commands ?

[...]
-----

*Very* nice Freudian typo there, Fabio ...

To answer your question in general (re SET BLOCKSIZE and other possible commands that could impact blobs or be impacted by them):

I have no knowledge about how this was implemented. Given Aleksey's response, however, I'm thinking that they leveraged the current memo-handling that occurs when you use NOCPTRANS (memo binary). So that would mean things like SET BLOCKSIZE and PACK MEMO might indeed impact blobs. But I am guessing.
