Internal structure of load modules
John Ehrman (IBM Santa Teresa Lab) has asked me to post the following:

On 26 Apr 1994 at 07:49:36, Peter Flass suggested that Kerry Tenberg
could find information about the internal structure of load modules from
several IBM manuals. I would offer this observation:
In March 1993, IBM delivered the successor to the Linkage Editor and
Loader, known as the Binder (part of DFSMS/MVS). The Binder supports a
new form of executable program, called a Program Object.
Rather than externalizing the format of the Program Object, IBM provides
a callable interface that can be used to extract information from the
Program Object. Information about the Binder and its interfaces can be
found in "DFSMS/MVS V1R1 Program Management" (SC26-4916).
It is expected that load modules will become less and less used, as will
the Linkage Editor. Thus, I wouldn't recommend making major investments
in programs that are dependent on load module formats.
