- *	Simple program to output integers or floats or chars between
- *	"start" and "finish", inclusive.  Default is an increment
- *	of +1 if start < finish or -1 if start > finish.  User may
- *	specify an alternate increment.  Also, user may left-pad
- *	output integers with zeros.  There is no attempt to prevent
- *	"infinite" loops.
