The RPG reference? OK, I'll look.

Allow Null and %NullInd are for file I/O, not SQL.

In SQL you create array of small int, one for each field in the data
structure. If null, array element is set to non-zero. All described in

the

manuals.

I'm doing an SQL full outer join of 2 files looking for exceptions both

Obviously there will be instances where one or the other of the files

has

nothing so the DS fields will be null. I've got a ALWNULL(*USRCTL)
statement. I've got an If %Nullind (iITNBR) in the code.

The compiler barfs trying to put ALWNULL on the DS definition. How do

I

specify ALWNULL on a DS? My googling skills are lacking today.

Thanks.
