Ooops. A small change in code :

>Then you should open the table lowlevel first and remove CDX reference.

handle=fopen("mytable.dbf",12)
>=fseek(handle,28)
><d>lnPokeByte = bitand(fread(handle,1),0xFE)</d> && Remove CDX flag
lnPokeByte = bitand(asc(fread(handle,1)),0xFE)
>=fseek(handle,28)
>=fwrite(handle,lnPokeByte,1)
>=fclose(handle)

Of course you should also check if you can have the handle and why not too.
