no i dont want them all on at once like when zone 1 has been used toggle that on soo it cant be used again so i dont get 1 + 1 then when zone 2 is used toggle that on so i dont get 2+2
just so it stops adding up the values wrong to stop my binary mask
. . . there's a reason why me and vart suggested the code that we did.
Here's an example:
It sets *only* that bit, nothing else.Code:unsigned char x = 0; /* x before: 00000000 */ x |= 0x08; /* x now: 00001000 */ x |= 0x04; /* x now: 00001100 */ x &= ~0x08; /* x now: 00000100 */
The binary mask will be fine, that's how you handle binary masks in C.

okky it sounds kind of what im after how do i go about doing it ?
. . . read the above message(s). Me and vart have explained this no less than 3 times so far.

. . . and I would have too, but it would put it over 500 chars.
Point is, we're here to help. We're not here to do your work for you.
Figure out as much as you can yourself, then come back once you have a solid question that actually merits some help. I highly recommend the link in my signature to Eric S. Raymond's "How to ask Smart Questions".

i dont want you to do it but you putting a peice of code in is not making me learn i dont understand the bit of code
Then what do you not understand about it?? Clarify. Elaborate.

you have
is x a int?unsigned char x = 0;
/* x before: 00000000 */
x |= 0x08;
/* x now: 00001000 */
x |= 0x04;
/* x now: 00001100 */
x &= ~0x08;
/* x now: 00000100 */
and will this stay toggled and not change any of the values when they are up?
and
Uhm... How come nobody has noticed that you are accidentally using '=' instead of '=='?
Code://try //{ if (a) do { f( b); } while(1); else do { f(!b); } while(1); //}
Correct. x, in this case, is actually an unsigned char, or an 8-bit integer.
When you toggle a bit to ON, it does not touch the other bits in the mask, no.
EDIT: I noticed that, brewbuck. Didn't think to mention it, because the whole thing seemed wrong.

because somebody namely me has noticed. But OP could not elaborate if it was really accidentally or intentionally
