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.
