That's an easy one - if I understand the question correctly. The Dec-10
(tops-10) had a linear address space (including the registers) so if the
pc was 0 - it executed the data in register 0 as an instruction. The
only catch is that there are a few addresses in the job data area
(something like 20-134) that you shouldn't mess with. Of course one
common falicy I made a couple of times was:

	move	reg,x(0)


Going back to your original posting - bleh. No actually I liked PDP-10
assembly language a lot. A lot more then 8088/68000 - and I liked DDT
a whole lot more than dbx.... Ho hum. 

This is a simple trivia question - but what does the following code do:

	move	1,[movei 1,@1]
	jrst	1

....
