computes the difference between the address of labels 'here' and
'there', takes the upper 16 bits of this difference, shifts it down 16
-bits and then mutliplies it by the lower 16 bits in register 5, putting
+bits and then multiplies it by the lower 16 bits in register 5, putting
the result into register 6.
