BASIC: THE FEELING OF THE GOOD OLD TIMES ! 10 INPUT A 20 B = SIN(A) 30 PRINT "ANSWER: ", B 40 END BASIC USER'S GUIDE: • PRINT 10 PRINT "HELLO WORLD !" 20 END • INPUT 10 INPUT “A=”, A 20 PRINT A 30 END • IF...THEN... Number Comparison: 10 INPUT A 20 IF A＞90 THEN B=“A” 30 PRINT B 40 END Conditional Operators: ＞ greater than ＜ less than ＞= greater than or equal to =＞ equal to or greater than ＜= less than or equal to =＜ equal to or less than = equal to == equal to ＜＞ not equal to != not equal to THEN can be followed by GOTO, GOSUB, INPUT, PRINT. String Comparison: 10 INPUT A 20 IF A=“TOM” THEN PRINT “BOY” 30 END Conditional Operators: = is == is ＜＞ is not != is not • FOR...NEXT... 10 FOR I=1 TO 4 STEP 2 20 PRINT “HELLO”, I 30 NEXT I 40 END STEP specifies the counter increment for each loop. If STEP doesn’t exit, the default increment is 1. FOR...NEXT... loop can be nested. 10 FOR I=1 TO 5 20 FOR J=1 TO 4 30 PRINT I, J 40 NEXT J 50 NEXT I 60 END • GOTO 10 ... 20 ... 30 ... 40 GOTO 10 50 ... • GOSUB 10 PRINT “H” 20 GOSUB 100 30 PRINT “L” 40 END 100 PRINT “A” 110 RETURN • SOUND 10 SOUND C, M, 0.5 The line 10 plays Middle C piano note for 0.5 seconds. Note: C, C#, D, D#, E, F, F#, G, G#, A, A#, B Pitch Range: L (low), M (middle), H (high) Lasting Time: specifies how long a note lasts. C, D, E, F, G, A, B can also be labeled as 1, 2, 3, 4, 5, 6, 7. (C# as 1#). • TEXT 10 TEXT “HELLO”, x, y, size (x,y): position of the string “HELLO”. • CIRCLE 10 CIRCLE x, y, radius (x,y): the center of the circle. • RECTANGLE 10 RECT x, y, width, height (x,y): top-left point of the rectangle. • LINE 10 LINE x1, y1, x2, y2 (x1,y1): the starting point of the line. (x2,y2): the ending point of the line. • POINT 10 POINT x, y (x,y): the position of the point. • CLR: clear the edit window. • CLS: clear the graph window. • DELAY 10 DELAY 0.5 0.5:lasting time in seconds This function is used to suspend execution of a program for a particular time. • CURVE 10 CURVE x, y, radius, 0, PI 0: starting angle PI: ending angle The curve draws clockwise with center (x,y). • Mathematical Functions: SIN(X), COS(X), TAN(X), COT(X), ASIN(X), ACOS(X), ATAN(X), SINH(X), COSH(X), TANH(X), ASINH(X), ACOSH(X), ATANH(X). SQR(X): square root of x. ABS(X): absolute value of x. FCT(X): x factorial. LOG(X): natural logarithm of x. LOG10(X): base-10 logarithm of x. LOG2(X) :base-2 logarithm of x. EXP(X): base-e exponential of x. ERF(X): the error function of x. ERFC(X): the complementary error function of x. ROUND(X) :integral nearest to x. CEIL(X): the smallest integral that is not less than x. FLOOR(X): the largest integral that is not greater than x. TGAMMA(X): the gamma function of x. LGAMMA(X): the natural logarithm of the absolute value of the gamma function of x. • Reserved Variables: INKEY : once a key is pressed, the value of INKEY changes. RND : a random number. PI : π • Some Tips: 1. Undo & Redo typing on iPhone with a shake. 2. Copy an Emoji or some character from other places (like Notes), then paste them on the edit window. 3. Exponentiation is expressed as X^Y. ## Key features - BASIC code interpreter - Interactive programming environment - Examples for PRINT, INPUT, IF/THEN - FOR/NEXT loops and GOTO/GOSUB - Graphics commands (TEXT, CIRCLE, RECT, LINE) - Mathematical functions - SOUND and DELAY commands ## Recent user reviews (10 of 17) All indexed reviews: https://appshunter.io/ios/app/basic-programming-language/id1114288994/reviews.md ### 5/5 — iPhone13でも使える *2026-01-23* マニュアルやexampleが丁寧なので、プログラミングしたことない人でもすぐにできるようになると思います。 iPhone13ですが、普通に使えています。ストアから消えると困るので書き込んでおきます。 同様のソフト（BASICやポケコン）が増えるといいなと思いますが、あんまり人気ないのかな？ 追記 剰余（%とかMOD）は無いのでしょうか？ 結構使う場面があると思うんですが無いとそれを実現するのに手間なので。 IF文の条件で!=と<>を使うとエラーになるか落ちるかで使えないのですが直りませんか？ 追記 剰余は2〜3行費やせば代替出来るとして、配列が無いのが痛すぎる。 DIMを使えるようにしてください。お願いします。 さらに追記 　上のタブが表示されず操作できない方へ 自分も同じ症状でしたが、「設定」の「画面表示と明るさ」の中の「ディスプレイ」の項目で、拡大表示にしていませんか？これをデフォルトに戻したら、本アプリ紹介の画面表示例と同じになり操作できるようになりました。 　OPENできない方達は、作者からの指摘どおり、ファイル番号を選べば開けませんか？自分は開けますが？ 　作者様←以前も要望しましたが、配列が使えるようになれば最高なんですが無理ですか？配列がないと出来ないことが多すぎて困ってます。 **Developer response:** 親切な言葉をありがとう。 ### 1/5 — 上のタブが操作出来ない *2024-03-21* iphone 11proでアプリを開くと画面上にタブが４個(File Edit Run Help)ありますがEditとRunがカメラとマイクの部分とかぶっているので操作出来ません。せっかく購入したのにタダのゴミアプリになってしまった。返金して欲しい！！ ### 1/5 — ファイルがopenできません *2024-02-10* saveしたファイルは表示されますが、openできないのでアプリが使えません。アップルは使えなくともお金だけはとるのでしょうか？ **Developer response:** Please enter the number to open. For example, if you want to open the first file, type in 1 and click "enter". Thanks. ### 5/5 — iPhone13でも使える *2024-01-23, version 1.5* マニュアルやexampleが丁寧なので、プログラミングしたことない人でもすぐにできるようになると思います。 iPhone13ですが、普通に使えています。ストアから消えると困るので書き込んでおきます。 同様のソフト（BASICやポケコン）が増えるといいなと思いますが、あんまり人気ないのかな？ 追記 剰余（%とかMOD）は無いのでしょうか？ 結構使う場面があると思うんですが無いとそれを実現するのに手間なので。 IF文の条件で!=と<>を使うとエラーになるか落ちるかで使えないのですが直りませんか？ 追記 剰余は2〜3行費やせば代替出来るとして、配列が無いのが痛すぎる。 DIMを使えるようにしてください。お願いします。 ### 1/5 — Does not work *2023-12-14* Unfortunately this does not work, as soon as you hit Run it exits app! ### 2/5 — basic *2023-03-22* openが出来ない。 どうしたらopenが出来るようになりますか？ ### 1/5 — 使えない。 *2021-07-03* iPadで使いたかったけど全く使えない。 画面におさまらないけどiPadでは無理？ **Developer response:** 最新バージョンに更新してください。 ### 2/5 — Disappointed!! *2021-05-23* Does not work on iPad running iPadOS 14.5.1. Please fix this. This could be a good app. **Developer response:** Please update to the latest version. ### 2/5 — Has problems *2020-06-13* Like many people I have my Ipad in a case with an attached bluetooth keyboard. This means I use it in Landscape. Unfortunatly your app only works in Portrait, oops. ### 1/5 — Doesn’t show properly on iPad Pro 10.5” *2020-05-13* The program screen doesn’t show properly at the left side of the screen. It is truncated. **Developer response:** Please update to the latest version. ## Frequently asked questions about BASIC ### What is BASIC programming?
