Reference files

["Sherry McMahon" <smcm@xxxxxxxxxxxxxxx>]

Hello everyone,

Thank you for the help with the OMIT option in the SAVLIB command.  It
helped me greatly and prompted me to order the 'CL Programming for the IBM'
book.

I have another situation I've been wondering about and haven't felt
comfortable with the answers I've gotten when I've asked programmers I work
with.  I've rewritten Sys36 programs in RPGIV and converted flat files to
400 physical files.  (Once again Scott, thank you thank you thank you for
your help) As I was doing this I saw other files, already AS/400 PF, had
reference files.  Everything I could read about reference files told me they
were just PFs.  I didn't understand why there were reference files then
physical files then logical files.  In my conversions (Y2K) I did away with
the reference files and made the system consistent with just having the data
in the physical files.  Originally some of the data was in physical files
and some in the reference files.   All anyone could tell me was this was the
SYS36 way and the people before me stayed with what they knew.  The fact
that I don't understand why these files were necessary makes me afraid I may
have done some harm by doing away with the reference files, although
everything is working fine.  As usual the books and online references aren't
clear to me.  Could someone give me some insight into this?

Thank you,
Sherry McMahon
