This depends on the compiling suite you are using.

Those provided by Microchip (C18 for 18F MCUs) usually define all available ports & registers in a header file specific to your device (something like p18F4550.h in your case).

In this header, you will have a structure definition corresponding to your specific port register. You can access to your specific RB7 I/O,within the following field : PORTBbits.RB7
