- Iron Age (Wikipedia)
The Iron Age is the final epoch of the three historical Metal Ages, after the Copper and Bronze Ages. It has also been considered as the final Age of the three-age division starting with prehistory (before recorded history) and progressing to protohistory (before written history). In this usage, it is preceded by the Stone Age (subdivided into the Paleolithic, Mesolithic and Neolithic) and Bronze Age. These concepts originated in describing Iron Age Europe and the Ancient Near East, but they now include other parts of the Old World.

GW-BASIC is a dialect of the BASIC programming language developed by Microsoft from IBM BASICA. Functionally identical to BASICA, its BASIC interpreter is a fully self-contained executable and does not need the Cassette BASIC ROM found in the original IBM PC. It was bundled with MS-DOS operating systems on IBM PC compatibles by Microsoft.
