// Keep in mind that strings in JavaScript are zero-based, so if you ask
// for Mid("Hello",1,1), you will get "e", not "H".  To get "H", you would
// simply type in Mid("Hello",0,1)

// You can alter the above function so that the string is one-based.  Just
// check to make sure start is not <= 0, alter the iEnd = start + len to
// iEnd = (start - 1) + len, and in your final return statement, just
// return ...substring(start-1,iEnd)
