There were several responses to my original question, (for which I am thankful), but they are nonetheless missing the mark.  The example shown at the bottom of this message from Finucci Domenico is a typical non-join multi format LF where each format refers only to a single PF.  This is not what I am interested in. 
Consider the following example instead.  Note that a single LF format is based on two PF's.
R    RFILE1    PFILE(PF01 PF02)
A    K    Field01
A    K    Field02
 
Files such as the one I describe above must be defined such that all the fields in the LF must also exist in ALL based on PF's.  My question is whether COBOL can compile and work with a file which is defined in this fashion.  I know the file could be redefined as a join to circumvent the problem, but the question still stands.

yes, it does.
Let's take an example and suppose we have the following LF
R    RFILE1    PFILE(PF01)
A    K    Field01
A    K    Field02
R    RFILE2    PFILE(PF02)
A    K    Field01
A    K    Field02
R    RFILE3    PFILE(PF03)
A    K    Field01
A    K    Field02
(the three PF share the same key structure ).
 
Your Cobol program is able to read such an LF with SEQUENTIAL, DYNAMIC and RANDOM Access as with a normal one. Remember that COBOL/400 supplies the register variable DB-FORMAT-NAME which hosts the name of the last format read.
 
Let me know if it's clear enough.
Yours sincerely.

Oggetto: Non-Join multi-PF logical file format

Can a COBOL program work with a non-join logical file record format which references more than one PF (more than one PF in the DDS PFILE entry) ?  I know RPG programs can NOT compile if they reference such a file.  Thanks.
