This might be a better question for the Midrange-L list.

The AS/400 is not, repeat not, an object oriented system in the
way you are
using the term.  The AS/400 has objects like files, programs,
data areas,
etc., and they do have properties like activation groups, maximum
records,
and format levels.  However, these objects do not "inherit"
properties of
other objects, unless one is talking about the members of a file
or if one
object is duplicated from another.  In the case of the former,
the
properties of a single member may not be changed without changing
those of
the file.  In the latter case, the properties of the newly
created object
may be changed without affecting those of the original object.

There are also modules that can be combined into one program
object.  In
this case many properties of the modules may be very different,
such as one
being RPGIV, another CL, and another C.  However, any properties
of the
program object, such as the activation group, are shared by all
modules.

I can't really comment on encapsulation as I don't think I
understand the
concept very well, but I don't believe the AS/400 is capable of
such a
thing.  I could be wrong, of course.

Hope that helps.

I can you quote examples (some situations)for all the
properties
of Object since AS400 is object oriented system....I would like
to
know various situations like Inheritance ,Encapsulation
etc(object
properties)how they happen in writing RPG programs....
Procedure and subprocedure Can be example for
Inheritance(inheriting properties from parent) right?I would
like
to know the situations for  remaining object properties like
encapsulation etc?
