Can't compile sample game

[yllawwally]

I just installed visual batari basic. I load up the zombie sample. I cannot get the sample game to work. What did I setup incorrectly. When I compile I get the following

Sometimes if one label wasn't found you end up getting a bunch of unresolved symbols instead of just the one. In this case I'm guessing that "mul8" is the culprit, because it's a routine found in the "div_mul.asm" include file, which is *not* included unless you tell bB to include it. Try adding the following line at the beginning of the program and compiling again:

 

  include div_mul.asm

Thanks that fixed it. It had an include fixed math statement, but not div_mul. I just assumed the sample would be correct, and I has messed something up in the installation.

It worked when it was first written, but later there was a bug introduced into bB in which multiplication or division by certain powers-of-two don't use bit shifting like they should, but instead use these general functions.
