Ran out of bits. Maybe I can grab a bit 7?

[+Random Terrain]

I found out that I need one more bit, but I used all of the ones I had available. If I can find a variable that doesn't go anywhere near 128, can I use bit 7 without any problems?

 

Edit:

 

I should probably mention that I know I'll have to ignore that bit. Would it make adding and subtracting a pain? Below is my guess.

 

If I want to know the value of a, I'd do this:

 

temp5 = a & %01111111

 

But I should be able to add and subtract the normal way as long as I don't go below 0 or over 127, right?

I tried it and it seems to be working fine. Unless there is a hidden problem I don't know about, this looks like a good way to grab some free bits without screwing things up.
