RE: CRTDUPOBJ on LF - how does it do this?

This has worked as far back as I remember (original S/38 days).  As long as
the LF and the PF reside in the same library, CRTDUPOBJ somehow "knows" to
link a copy of the LF with a PF in the copy library.  It's very handy, and
one of the primary reasons we did everything possible to stay away from
"cross-library logicals".  Creating copies of those monsters was nasty,
usually requiring manual ADDLFMs.
