}	What exactly do you/they mean by object oriented. Are we
}talking something along the lines of the intel approach ?

	    The AS/400 architecture makes the VAX architecture look
	    like RISC--it is *so* CISC!!

	    As I understand it, there are 2 levels of microcode.
	    Your instruction (I was told one instruction was
	    "create database") executes the top level of microcode
	    which in turn executes the bottom level of microcode
	    which in turn actually causes the hardware to do something.

	    Most unusual.
