<p><b>New page</b></p><div>'''Program compatible''' is a term applied to either a new [[hardware]] system (such as a [[Central Processing Unit|CPU]] or [[device controller]]) or [[software]] system (e.g. an [[operating system]]) which is so functionally identical to an earlier one that [[program]]s written for the earlier one will run with the new one with no changes.<br />
<br />
It usually means that the original [[object code]] can be used as-is, but sometimes [[compiler|re-compilation]], or some similar step, will be needed.<br />
<br />
One early, famous, example was the [[IBM System/360]] line, in which it was a deliberate design goal that almost all the various CPU models were program compatible, so that a customer whose processing needs had grown could trivially upgrade to a more powerful model.<br />
