  This is a typical place for making a mistake in the SDL syntax (and
perhaps would reserve an entry in the povQ&T page).
  The right way of doing this is:

#macro Return_Int (A)
   #if (A>0)
     #local retval = A;
   #else
     #local retval = 0;
   #end
   retval
#end

  The reason for this is because how the parser works... But it's a bit
too complicated for me to explain this late at night. :)
