AutoOpen index file ??

Hi,
using Clipper 5.2.e since 1995. The file DODLIST.DBF is opened with INDEX
DODLIST.CDX, which contains 3 orders. Somwhere in application I want to
build a temporary index with FOR expression with the same 3 orders, to show
only the part of records. Here is the code, DODLIST is the current workarea:

cTmpNtx1 := "Temp111.CDX"
DBCLEARINDEX()   && close the zoznamdl.cdx -> works O.K., no opened
index file

INDEX ON (dodavatel+cislofakt) TAG CisloFak TO (cTmpNtx1) FOR;
RIGHT(DTOC(DatumDod),7) == cObd

DBCLEARINDEX()
INDEX ON DTOS(datumdod) TAG Datum TO (cTmpNtx1) FOR;
RIGHT(DTOC(DatumDod),7) == cObd

DBCLEARINDEX()
INDEX ON Doklad TAG Doklad TO (cTmpNtx1) FOR;
RIGHT(DTOC(DatumDod),7) == cObd

CLOSE INDEXES

SET INDEX TO (cTmpNtx1)

All works fine: after CLOSE INDEXES the debugger shows: the workarea is not
indexed -> O.K.
but
after SET INDEX TO (cTmpNtx1) the debugger shows the workarea has 2 opened
index files DODLIST and TMP111 and 6 active orders !!!!
I have 2 questions:

1. Why is opened the DODLIST.CDX ?? It seems, like the Autoopen feature of
CDX driver in Visual Objects, but I did not read about it in documentation.

2. How can I close only one order bag, in this case DODLIST? The NG says
about the next order managment functions:
- OrdlistClear() - closes ALL the indexes
- OrdDestroy() - removes the specified order from the order bag

To my knowledge that doesn't work for the 'DBFCDX' implemented by Successwar
e which the 'DBFCDX' RDD
driver in 5.2 is based on (SIX2) (not sure about COMIX as I haven't tried to
 do it).
ie - You cannot close the structural index and keep the DBF open.

That is correct in regards to 5.2+Comix.  The only way to close a structural
index is to close the dbf, turn off autoopen (cmxAutoOpen(.F.)) and reopen
the dbf.
