RE: Map Null Indicator to DS in trigger program

I was looking for an example program where I have done this, but I don't
have it anymore.

The solution I used, was to do use API QUSLFLD to list the fields in the
file. Then I used the map along with that output to determine what flag was
associated with which field.

I've searched on Google for some easy solution to this, but it seems
there's nothing about.

We're starting to use Null-capabel field in or DB mainly for RI-related
needs. Everuthing's goes ok, except for a trouble.

We use a lot trigger program to perform sone calculation based on
changed to data. Usually, we defined the trigger in a way that allows
change to PF to be transparet to the trigger: just recompile the
trigger
(we've wrote an in.house proc that update the PF, recompile dependecies
and trigger without need to remember to do it) but, using null map
indicator, i didn't have any way to match the null-indicator to the
file-based DS. i just need to *count* the fileds and then say "if
NullInd(x) then".

This is oblviously prone to error if a field will be added *before* the
null-capable fields (and, of course, causes the code to be less clear).

Is there any way to map the null-field map to the DS ??? since the DS
iself is declared basing on the file, it has the field null-capable, so
i suppose it has it's' own null-field map, and ti would be nice to be
able to copy or override this with the one coming from the Trigger's
parameter.

Any hint will be appreciated. Thanks.
