Abacus in your pocket! I don't like the colors, but otherwise, it's functional. I use waterdrop as sound.

It's so simple and easy! This is a good beginner project.

Here's an optional extra. You'll need to add DIM M[] somewhere on the first screen, but I'm sure you'll figure it out. M+ doesn't really add, though. It just stores the value.

And here's the updated screen. Wow. Looks just like a real calculator. Display on top screen can be better, but I'll leave that to you.

I also fixed it up so the top screen is double width as well. Looks nice!

Hi Harry: All ur SmileBasic posts look SO cool....make me want to buy game!!!! I checked it out in E-shop & so affordable!!! Thanks!!!!

Great! I hope you like it. Leaving Pokemon Shuffle gives me a bit more time with SmileBasic. :D

Ever consider entering the Ogiri Contest with your OSPs (one-screen programs)? They accept multiple entries as long as each is for a different category. I think these OSPs will benefit folks more if they're featured on the website rather than getting flushed away by the constant Miiverse posts. http://smilebasic.com/en/ogiri4/

Thx again...i leaving Shiffle too...(same "patterns” in game) & high number of players using unsupported cheats (&say'n they dont) ruin'n "fun”. You make Smile Basic look awesome, thanks again!!!!!

* oops Shuffle (not Shiffle)

OSPs in Ogiri? I'm not sure they'll be happy evaluating dozen of programs for the comp. :p

Now with colors! I had to change the loop a bit on the first screen.

The top screen holds your computations. The stripes moves up with the numbers, making it easier to see. It took me quite a bit of trial and error to get it. I'm sure somebody who is good at math can do it easy. Who says you need to be good at math? :p

And here's the bottom screen. All the colors are console colors, using COLOR command. Rather harsh. I still prefer it to Black and White version.

Here is the second screen. Apparently, there's a bug in memory function. Oops. Fixed.

Here is the third or coloring code screen. The way it's done, it causes jittery screen, but it was done this way so that I can code it one screen at a time. Very useful coding technique for a busy person. :)

Maybe not a whole dozen, but pick your Best 5 and make a selection screen titled "Harry's OSPs" or something along the lines. At any rate I do hope you enter the contest one way or another. I just think skilled folks like you deserve to be officially recognized, and the Japanese do need NA competitors this time.
