Re : Multiple company support on OS/390

We support four companies data in some of our systems (our own and third
party processing for three others).

We use one subsystem, but multiple tables with different schemas. We
use "SET CURRENT PACKAGESET" to switch to the correct set of tables. We
use a "business rule" table (actually it's an IMS database for
historical reasons) to supply the value for this for each company.

We use exactly the same set of programs for all companies - this was a
conscious business decision to reduce complexity. So if one company
gets new functionality then they all do.
