For example: This is a numeric example: var i = 0; while(condition){ window.write('We are at '+i); ++i; } Essentially, I want to count with letters, like Microsoft Excel does, instead of numbers. So instead of printing "We are at 0", "We are at 1", "We are at 2", etc., I need to print "We are at A", "We are at B", "We are at C", etc. To mimic Excel (the only example I can
