Jun 12, 2016 at 17:11 comment added mckenzm I was thinking of "saturated values", where the result is capped at a limit. The idea was code could be simpler if it did not have to include boundary and overflow tests (in graphics to avoid cycling or going positive by travelling past limits of negative). PSUBSB/PSUBSW. I concede the mechanism may not be the same, but the effect and the intent of the function is.
