Hi PICsters!

For a while I moved from assembly language to this C compiler from CCS
(as it was given to me free by somebody who got fed up with it).

I'm getting on quite well with it, but I'm stuck now on the WRITE_BANK
command.

Am I correct that this command can be used to output a byte to the I/O
ports?

I have not managed to do so, and I would like someone to give me an
example of how to output a number to, say, port B.

If I have misunderstood this command, please tell me what is the command
to output a byte to an I/O port.

Regards,

Francesco Cembrola
