Thanks for raising this.  We will obviously try and sort out the problem as
soon as possible.  I will leave it to Mark Koennecke or Przemek Klosowski to
comment on the best way to deal with the specific bug.  As soon as we have a
fix, we will release an updated version.

Which documentation are you referring to?  The most reliable and up-to-date
documentation will always be the web pages.  I've just checked that they all
give the correct description of the meaning of the size variable (at least
in NXgetslab).  It's true that there was some confusion about the meaning of
the second variable in SDreaddata, but that was cleared up quite a while
ago.  I suspect you are referring to NAPI.TEX, which has not been updated
since the first release two years ago.  Perhaps I should remove it from the
distribution until we've updated it.  It was only meant to document the
design philosophy of NAPI, and should not be used as a detailed reference of
the latest version.

Thanks again for reporting this,
