Actually, testing for "absolute" equality/inequality is exactly what the C++ 
standard template library uses for its iterators.
When using non-integral types (float, double, long double), you cannot use 
absolute equality.  When using integral types (everything else), you can.  
When iterating (pointers, usually), it's often a good idea.  Sometimes it's 
the ONLY idea (when iterating through, for example, linked lists?).

I realize this is the C_ECHO, not the C_PLUSPLUS echo, but these guys at HP 
aren't exactly newbies.  :-)
However, in this particular case, convention wins out, and count < 6 should 
be used.  :-)
