RE: Need some advice

This is true. In the earliest days of the S/38 everything on the machine was
referred to as an object of type "x"...

I think we work in object-oriented ways more than we know. For one
thing, consider the object-based design of the S/38 - AS/400 - iSeries -
i5 and you will have some groundwork. E.g., a *FILE object could be
considered a class - I know, it's deeper than that, but let's keep this
simple - am just forming this on the fly - and a *FILE object has
certain attributes at what we call file-level (file level identifier os
one). ALL *FILE objects have these same attributes.

Now on the iSeries there are also methods contained in every object -
things you can do - you can't write to a *PGM but you can to a *FILE.

That's the beauty of the OS. It was designed from the very beginning to
be object based. It's one of the key design elements that makes it more
hack resistant than anything else out there while also being easy to
extend. Have you ever read "Fortress Rochester"? If you read through it,
you'll come to the conclusion that all of the so called new and hot
technologies (object oriented, virtualization, etc...) were implemented
on IBM midrange systems long before they were popular on so called
modern OS's.
