Yup! I just typed it in on my 1261 to test (it's basically identical to the 1262). I think this will work on nearly any Sharp, though the "=" label depends on having the user-definable keys and AREAD available, which a few models lack (PC-E500, Sharp Wizard BASIC cards...). The GOSUB routine probably would still work the same, though.

Code:

' <expr> DEF-S scientific notation with #=? decimal places ' <expr> DEF-D fixed notation with #=? decimal places, may cause error if value exceeds 1E10 1 "S" AREAD X: USING: INPUT "#=";O: PRINT USING LEFT$("##.#########", O+3)+"^";X: END 2 "D" AREAD X: USING: INPUT "#=";O: PRINT USING "###########."+LEFT$("#########", O);X: END

Works on other Sharp PC, but unfortunately not on the PC-1211. Allows the output to be used as an answer to continue calculations.

One of the reasons I kept using the Sharp pocket computers is because it was so easy to add features. Modern advanced calculators like the wonderful HP Prime have everything already built-in of course

That's a clever way to do it. You could probably get this to work on the 1211 by using a calculated GOTO/GOSUB and a bunch of different sized string literals, but it wouldn't be terribly efficient in terms of RAM usage!

I agree that the Sharp models are nice for customizing by adding small routines like this to memory. I just wish they had something resembling the multiple program spaces of Casios, and a simple way to overload/switch your DEF key assignments on the fly.
