Pretty interesting machine, if you study its
instruction set, BTW; with
no stack, subroutines are 'interesting'.
Not much worse than the PDP-8 :-) Plant return address in first word and
jump to the second word; to return, do an indirect jump to the first word.
Recursion was possible. but I think you had to emulate the stack.
