disassembling

I'd like to go through a binary file my teacher gave me line by line to check addresses on the stack and the contents of different registers, but I'm not extremely familiar with using gdb. Although I have the C code, we're supposed to work entirely from a binary file. Here are the commands I've used so far:

(gdb) file SomeCode

Which gives me this message:

Reading symbols from ../overflow/SomeCode ...(no debugging symbols found)...done.

Then I use :

(gdb) disas main

which gives me all of the assembly. I wanted to set up a break point and use the "next" command, but none of the commands I tried work. Does anyone know the syntax I would use?

I compiled GDB 7 on a Mac OS X Leopard system.
