The website I made looked somewhat crude, but the my dadРІР‚в„ўs friend liked it and I was proud of it. I took that offer and spent two months learning HTML and CSS, as well as GIMP and Inkscape so I could make the background image.

So I delved deep into the inner workings of the PRIZM, managing to brick three of them in two years before Casio got suspicious and stopped sending replacements (though I hadnРІР‚в„ўt voided my warranty).Р”Р„round the same time one of my dadРІР‚в„ўs friends wanted a website built for his company and my dad asked if I wanted to try building one for him. I took the course, and a week later my beautiful PRIZM was waiting for me in the mailbox.

Casio started a promotion where they gave away free PRIZMРІР‚в„ўs to people who finished their online training course. It had colors! I had to have one, but I knew no one would justify $99 on another calculator when the one I had was working just fine. I wrote a couple libraries to help other developers who came my way. I couldnРІР‚в„ўt wait for the first release, and probably pestered the developers much more than I should have (to the point where I am surprised they continued to put up with me), but it finally came.Р”Р„nd then I dove into Lua. This wasnРІР‚в„ўt the end though, because a couple weeks later I came across a thread on a french calculator forum announcing development on a Lua port for the fx9860GII. I ended up going back to good old BASIC and optimizing the programs I wrote to try to improve their speed. Most of the default libraries that online C tutorials referenced were not available or were named differently, and the documentation for the SDK was somewhat obscure. So I installed a third-party custom ROM with the addin feature flag set to true, and got to work learning C.

After googling around a bit I learned that the hardware on my calculator was actually the same as the hardware on the fx-9860GII, which had an SDK for developing addins for it in C. Since I wanted to program games for it, I started researching other ways to program calculators. I had also begun to realize that CasioРІР‚в„ўs BASIC dialect was pretty slow for anything other than math. I had learned from some friendly people on the Universal Casio Forums that using goto was usually a bad idea, and had started using loops and subroutines to organize my code. As much as I hate to admit it, it used goto instead of a while loop.Р”Р‡ast forward a couple months. My next program printed РІР‚СљYay I can code!РІР‚Сњ over and over and over again. It took user input, assigned it to A, and then printed the square root of A at position 1, 1 on the screen. My first program ever was named SQRT, and it looked something like this: Well, right there I decided I was going to program the thing (there was no tutorial, just a syntax guide and documentation of the built-in functions). After getting through the calculating and graphing sections, I came across a chapter I didnРІР‚в„ўt expect to see, labeled РІР‚СљProgrammingРІР‚Сњ.

The first thing I did was start reading the manual from page one. It was given to me on my 14th birthday and I was overjoyed.

This is a Casio fx-9750GII, the device that first introduced me to programming. If you donРІР‚в„ўt want to read the long personal story of my relationship with programming, you can take the elevator another floor down. Hello?Р”Р‡or those of you who stayed, charts like this are just about the worst way to choose a programming language. Hey, come back! I was just making a point.

Use this chart to decide your first programming language.
