API QDBRtvFD and DDM files





Hello, maybe (and hopefully) anyone can help me; searching the net didn't
gave a suitable answer.

It concerns reading file information for DDM files: i can't even decide
wheater a file is a DDM file or not.

Using DspFD a file has the following attributes:
   system: *lcl
   file type: device
   device type: DDM
and DDM attributs are shown.

So far, so good. But I'll get these information with API QDBRtvFD.

In format Qdb_Qdbfh, positions 68 to 69 (counting begins at zero) is field
Qaaf2 (additional attribute flags); bit 4 (counting also begins at zero) of
the second byte should by ON if it is the a DDM file. But this bit always
is OFF: b'0001 0000'.

Where is the error?
