Patrick

These few records were added by DFU, just for testing.

If I add records using RPG setting the date fields to null;

        Eval      %NullInd( ScCed ) =  *On

The test works fine using %NULLIND

        If        Not  %NullInd( ScCnt )

So it must have been the way DFU created the values for these fields !

Thanks for everyone's replies.

I'm glad you ran into this. I ran into it a couple of months ago. Seems
that you can put a value in a null capable field and leave the null
indicator set to *on.
At the time I started a thread asking if the 'eval' statement handles null
values. It doesn't. The reason I thought that it did is because I could DBU
the file and see the values that I put in the fields, but if I viewed the
same file by SQL it would show me the null values. (I hope I remembered
this correctly.)

When ScCnt was first assigned a value, was the null indicator handled
correctly or was it always being turned off?

I'm using ALWNULL(*USRCTL), but the

If        Not  %NullInd( ScCnt )

test always seems to be true even though some dates have a null value.

Thanks.

Hi Andy,
  NULL is not a value you can assign to a field, so *LOVAL won't work.
NULL
is an attribute, like size, text and edit code.  You should be able to use
%NULLIND for this as long as you specify ALWNULL(*USRCTL).  What trouble
are
you running into?
