Re: Reference files

Sounds like the reference files served as "data dictionary" files.  We do
the same here.  For each application we write (billing, G/L, etc.) we create
a field reference file, with one record format, one member, and 1 record
(SIZE(1 0 0)).  Then, all PF, LF, DSPF and PRTF files "refer" back to the
field reference file for field attributes.  Clean and straight-forward.  You
have one place to look for field attributes.  Hope this helps.
