Do it in the same way. See this post for an example with the 18F452:

pcm

i did that, but i thought that was wrong.. because help docs says that #byte is 8 bit long.. but.. anyway..

thanks for the help.


regards.

The #byte declaration, declares a 8 bit variable _at_ a location, that can be anywhere in RAM. 'PortA', is still only 8 bits long itself, it is the address that has got larger. :-)

Best Wishes
