As far as I know, this refers to the disk transfer buffer size.  I
don't know any advantage to changing the default value (which is, I
think, 512).

No, I haven't actually tried it yet, myself.  And I suspect that DJGPP
are not expecting or searching for an alternate size bigger than the
default.  I would think, from the description in the SDK, that it was
available to all usage, not just to bat files called by other bat
files.
