Read BCD Value on MSB of Port B

[whmeade10]

I have connected a 10 position BCD rotary switch to B4-B7 and
need to be able to place the value into a variable. When I
programmed in PIC Basic Pro this was pretty straight forward:

BCD_In = PORTB & \%11110000 ' Read BCD switch on ports B4-B7

I haven't been able to find anything simular in PIC-C.
Thanks in advance..

Everything you have to do is:
1 - First declare PORTB
#byte PORTB = the actual portb addr
2 - Read the port to the variable
BCD_In = PORTB & 0xf0

That's it.

Thanks for the quick response. It is easy.

I wuld also like to appoligize for all the multiple posts on this subject. I kept getting server error pages when submitting my question. I guess they went through even though I got an error. I also noticed that I can't view some of the replies to my questions.
