Paul: re: your semantic point I was going to say that the result set is indistinguishable from a left outer join but that isn't true, is it? We don't have single records with all the header and detail fields, we get a header record then detail records. If there are headers without matching details, we see those. If there are details without matching headers, we will see those as well. Just because we have a detail record, that is no guarantee that the values in the header fields are for a matching header record, we must check. Thank you for pointing that out. The difference is subtle until one thinks about it.

If a field is showing as blank, then that means that the field is blank on the physical file. You should be able to check it with Query/400. Assuming that the problem is with the WUDEPT format, select the file in Query and specify the format. Spot the record with the blank field. Now run a query on the Physical file and check the record. Assuming that both are OK (i.e. there is a value in the field), then the problem lies in the program that is processing the file. A small point (semantics) - this logical is not joining two files, it specifies a union between the two files (a merge). :-) HTH Paul Tuohy Scott.Wolf@helpsystems.com wrote: > I'm a newbie to RPG/400 and have learned much from this mailing list. > > I do have a question to offer up to all the gurus. > > I have a multi record format logical file that I am using.
