Re: Blocking I/O (was: Expensive op codes)

["Eric N. Wilson" <doulos1@xxxxxxxx>]

Hello Peter,

The four database I/O programs are in your QSYS library, They are not MI
instructions though. They are not documented as far as I have been able to
find.

QDBGETDR    *PGM      QSYS  Probably Get Direct
QDBGETKY    *PGM      QSYS  Get by Key
QDBGETM     *PGM      QSYS  ???
QDBGETSQ    *PGM      QSYS  Get Sequential

There are a ton of QDB* programs... many are pretty easy to divine what
there purpose is others well who knows :-)
