Programmable calculators don't tend to have file I/O, but they do have useful programming languages. For example: the HP28 basically has an embedded Lisp interpreter, but it lacks explicit file I/O capabilities. In the HP28, persistant storage is handled by making everything persistant. No heap allocated object ever goes away (even across power cycles) unless the garbage collector identifies that it can never be reached. -Mike -- http://www.mschaef.com .
