Perhaps the difference between using '-' and '~' relates to the fact
that you are trying to create two different entities (0 and ~0) logically
whereas 0 and -0 are the same numerically. Seems irrelavent either way..
Also, while Im not aware of any implementations of C on a 170 series
machine I do know that APascal (ascii version of Pascal-6000) represents
characters as 7 bits, allowing 8 per word. As the machine has no
character instructions (we'll ignore CMU) so converting a character
pointer to Word_Address and Character_Index is much simpler with a
mask and a shift of 3 bits then pulling odd shift/add/mask/munge to
divide by 7, and with an 18 bit address range packing 4 per word
wipes away what little memory you have.. Of course, CDC has moved into
the world of 8 bit characters and 64 bit words with the 180 series,
so again, its all pretty irrelavent.

I know this is wasted net time, but does anyone have a PD C compiler
for a 170 series machine? Didnt think so.....
