Search for "ISO2709". It is the layout of the record.

Hi Jean Pierre,

	After christmas we come back to work. I agree with
you is very usefull
for the yaz Delph implementation that we share our
experiences and
problems here.

	I talked with Rodrigo Kiguti and he explained for
me the problem with the
name of functions. As Giannis Kosmas said the Call 
to GetProcAddress was
incorrect.  I  replace the substring " at "  with
"" and my problem of
ACCESS VIOLATION is finish.

	I did a connection with a server Z39 without
problem. The Record Count of
a search is correct too. My problem now is how to
read the detail of each
record and put it on a STRING GRID?  Look the
program:

   FHOST := 'z3950.loc.gov';
   FPORT := 7090;

   q := 'attr 1=4 attr 4=1 "A brief history of
Merthyr"';
   type_spec := 'raw';
   q := UTF8Encode(q);
   r := ZOOM_connection_search_pqf(ZOOM_connection,
PChar(q));
   fRecordCount := ZOOM_resultset_size(r);
   ShowMessage('Recuperou ' +
IntToStr(fRecordCount)); // This line is OK

  // Loop

      for i := 0 to fRecordCount - 1 do
      begin
            ZOOM_Rec := ZOOM_resultset_record(r, i);
            zraw_record := ZOOM_record_get(ZOOM_Rec,
PChar(type_spec),len); // ZRAW_RECORD is NIL, what
is the
problem??

           …
      End;

       I need to Know how get the DETAIL of each
RECORD and show it in a
STRING GRID this way:
