(I'm replying to my own message) I tried setting bit 0 of ZS_BITS and until
now I didn't realize why it worked. It has to do with the fact that bits 0
and 1 are not the same .... I was forgetting that it was binary, and so I
was thinking that setting it to 0 did one thing, while setting it to 1 did
another, but because it is binary, I have to set both bit 0 and bit 1
...(Duh! I wonder why I didn't think about that? Maybe it has something to
do with the fact that I did it at 5:30 a.m. - hint, I did not get up to do
it, I was up all night and morning). Anyways, setting bit 0 at the beginning
of the program fixed it. (I wrote this in case anyone else had the same
problem).
