There is no SIZE? command in this calculator.

This is a question people had been asking since the machine was introduced. It was solved relatively early on in the PPC ROM with the "S?" (Size Finder) routine, which contains a call to another routine within the module. If you can't get your hands on a PPC ROM module, perhaps others here can chime in with a reasonable alternative.
