It's most likely complaining about rowstr.length not being a constant, not  
the '-'.  This works:

const char divider[5] = '-';

If you want to allocate a new array on the heap with '-' in it, I think  
there is a way, but I'm not sure how to do it.  I'm pretty sure there's a  
runtime function to do it.
