Actually, it does... I think that posting a little more details about your code would help...
What make you think that it doesn't work?

It won't work, if 'x' is an _unsigned_ integer. Remember the default 'int' type is unsigned...

Try:
signed int8 x;
that should make 'x' be valid from -128 to 128. If you omit the 'signed' portion it makes 'x' valid from 0 to 255. That one bit me when I first started using CCS.

How about -127 to 128 instead of -128 to 128? I'm sure that's what you probably meant anyway  |

Ok, Ok. Got some smart ones out there.
I guess I'll just walk over to the bit bucket and toss one in the garbage to make it and even -127.  |
