Oh well, that was what I was trying (apparently not very succesfully ) to
describe, without going in too much detail.  Although I couldn't remember
the technical term for the technique.

But how would you get into the first cycle then?  Before you could do

Well, precisely that, I think.  No OO, no inheritance, no polymorphism, no
'in' things.  Just simple and useful, how boring.  Maybe we need a new
syntax: CustMast := new PrimaryFile('CUSTMAST', '*LIBL') looks much more
modern, don't you think?
