Assembly

Hey /prog/, I am learning Pentium Assembly on linux, using nasm assembler. I've been having trouble with the stack operations. Could somebody explain how I can simply push 4 integers(hex/dec) onto the stack, and then later pop them off? I get some really weird messages when I try to do this.

Thanks a lot.
