Hi Mark
sorry for my typo errors

i understand the sub-bussing technique
yet

on the appendix:
   Output Pins Each output pin of a part may feed one of the following destinations:
   * an output pin of the chip
   * an internal pin

so, internal output can be wired only once

and the example code i previously attached , shoe that i had to use the same combinatorical for outputing the ALU function output
and again use the same wasty comb. to create the ng pin

even if i had sub-bussed it, i still was missing the output msb


regards
