iPad Mini 5 support

This program doesn’t work on iPad Mini 5 with IOS 13.1.2.

Doesn’t show properly on iPad Pro 10.5”

The program screen doesn’t show properly at the left side of the screen. It is truncated.

Disappointed!!

Does not work on iPad running iPadOS 14.5.1. Please fix this. This could be a good app.

okay

this is the best BASIC emulator i have seen in app store. but severely limited because of tiny text window. does allow interactive input. nice sound function. Please enlarge the size of the text window in the next upgrade, especially for ipad where we have a huge screen compared to the iphone. Consider using the native ios keyboard and allowing us to hide the graphics windows. Also how do i see the full list of programs i have saved if i save more than 4 programs?

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.
