Thanks for the language correction. However the compiler is braking.
Here is some of the code and the error messages reported in compilation.
I have tested this on two different computers and the same error messages were
reported. When I changed the _N to N or something else the
compilation continued
on to the next error. Hence it is an underscore problem.
g++ -Wall -I. -I../misclib/ -I../graphicslib/ -I../mathlib/ -c

Thanks for your response, I will think twice before using an
underscore, even though
I do no agree with it being reserved. It is very important to have
programs that
compile across other platforms.
