Hi Trevis, > should I even be allowed to declare "larry" in both foo.c and > bar.c ? If so, why is that not seen as a problem? You can declare larry as many times as you want. You've declared it in main.c and in bar.c. You can only define larry once. You've defined it in bar.c. If you change the declaration of larry in bar.c to a definition, then you've defined it too many times (i.e., more than once). HTH, --Eljay
