I am using Xcode...not that that probably makes any difference.
Initially arr[2][13] is declared as a char array. In the debugger
window, there is a column for value and the "initial" value of arr is
"2". If one expands this, then one sees 2 arrays of 13 elements, and
as you say below, these seem to be contiguous. I was trying to find a
way of seeing what the address of each element is, but have been
unable to do so....

thank you Barry.
