function doNothing()
{
  return;
}

this will return 'undefined' which can easily be tested for.

function doNothing2(some_condition)
{
  if(some_condition)
  {
    // your function body
  }
}

this will also return 'undefined' if 'some_condition' is not true.

i guess what i'm getting at is there isn't really a way to make a function
that doesn't return anything at all.

can you explain in greater detail what you're trying to do?

thanks,
