Re: 2 formats in a LOGICAL

This is definitely a question for the RPG list here. You are dealing with a multiple-format logical file. This is not usable by SQL, as far as I know. The "good old way" was to specify as a keyed file, then CHAINing or READing as you would for single-format files. But you a record identifier that you check on each read to see which one you are reading. That is specified in an I-spec, IIRC.
I recommend the ILE RPG Programmer's Guide at www.iseries.ibm.com/infocenter for details. Look up "multiple format logical files" there. 

And ask the folks on the RPG list, who probably have better memories than I.

HI I have to use a logical that is composed of 2 files (PF), let us call
it Logfile. The names of the fields that are designated as Keys, are the
same. I am not sure as to process this in RPG. Do I use the READ LOGFILE
method, am I going to get all records. Is there a better way to obtain the
data, perhaps via SQL?

I will need to allow the users to either Change some of the fields in this
file, or to Delete a record ( but no add).

Thanks,
Steve
