// function	pick_ul
//
// purpose	Pick an unsigned long from the given arguments based on the
//		value of the first argument.  The first choice from argument
//		2 is chosen with an index value of 0.
//
// arguments	1 (int) choice index value
//		2..N (unsigned long) values to choose one to be returned
//
// returns	(unsigned long) the chosen value
//
// warning	An index value that has no corresponding value will have an
//		undefined result and probably disasterous consequences.
//		THIS CONDITION CANNOT BE PROPERLY TESTED FOR.
