Problems running homoplasy test (negative homoplasy results)

[Robert Wolfgang Rumpf]

I am attempting to use John Maynard Smith's Homoplasy Test software, 
and am getting some curious output.  The datain.bas seems to run just 
fine, and the exph.bas program gives normal (well, reasonable) values 
for certain data sets, and for others I'm getting negative homoplasy 
values (and thus ratios above 1).  Any ideas or suggestions as to 
what I may be doing wrong???  Thanks...
