Souns to me that he wants to use the same pair of macros over and over again and
therefore a single "global variable" to hold the array size wouldn't be enough.

I think testing for #ifdef(myArray[i]) is quite an elegant solution for the
problem: You just need the array, nothing more. "Global thinking" may be easier
for a quick hack, but is usually not so elegant in the long run. It's often an
obstacle when you want to turn code into a re-usable macro.
