If you want to learn more about YACC and BISON, then have a look at a C like
grammar (you'll not need a full C/C++ grammar). The semantic code may be
simple, depending on the "commands" in your text file. For your example you can
use a global variable for the memory address, where every parsed number is to
be stored, and afterwards the address has to be incremented (*addr++ = nmbr;).
