A member is like an Individual file.It is possible to Have
32767 such members within the same PF.Each member added to
the file will exactly get the same record format(
fields,types and KWDS) on the file.This facility is
provided to meet the requirement when many files are needed
to be created with same structure.Here just Create file
once with MAXMBRS(as many reqd) and ADDPFM will do it.Easy
to create and maintain as a single object.Each member is
identified by unique name within file.
Examples : A School has attendance register per class. Each
Class has 4 sections and in all10 classes. Instead of
Creating and maintaining 40 files and scaterred in a
library, one can create a PF and add 40 members in one
object.
Secondly All Physical files created need not necessarily
have members. Some files are created to store field
definitons only and are called field refrence files. They
need not have members.
