The PL.8 language was specified to always produce a positive mod. Of
course, that may be what happens when you get a lot of compiler writers on
the project :-) Another important point is that weren't designing for a
particular machine; rather they built the machine and the language
together (and the 801 had no hardware support for division anyway).
