Array of bits

When I try to create an array of bits, which would be very efficient ( at least for me ) CCS warn me saying that is not allowed. Why?
I need to create 1 array of 42 bits and send them through output_but();
I saw here in the forum someone who created an array of byte and mention that is efficient ...
Any comments or suggestions , thanks a lot

Arrays of bits are supposed to be supported in the new V4 release but given the bug level it is exhibiting right now I wouldn't use it for production software.

You can write your own functions to get an array of bits out of an array of bytes. There will be performance penalties with all the mechaniations required to access individual bit indicies though.

Or you could try a union and structure. Still going to have some performance penalties.
