If you do not have any select/omit logicals, you don't need to
change the derived-index item in QAQQINI. You want to look, though,
at the IGNORE_DERIVED_INDEX entry - all the entries are set to
*DEFAULT, what you should do is look at the description in the file.
Use RUNQRY () QAQQINI, DSPPFM doesn't show it, since the description
is in unicode, I think.
Do NOT change the model file that is in QUSRSYS or in QSYS. Make a
copy of the one in QUSRSYS (I think - what you read will tell you)
and modify that.
