	Not too good, I'm afraid. The loop1 label is misplaced - you "clr i"
on every iteration. Also #10 is octal 8 instead of 10. You probably don't want
the colon at the end of the "bra" statement. You don't want "bge out" but
"bgt out" (since you say i <= 10). And finally, i and j should be local
variables on the stack. I can see why your professor laughed.
