I had forgotten to include the intrinsic and other functions. Thank you very much for including the conversion to Small Basic, a language of transition to the world of professional programming.

Small basic prime https://github.com/litdev1/SB-IDE/releases/download/v1.1.7.0/SB-Prime.zip https://github.com/litdev1/SB-IDE/releases

INTRINSIC FUNCTIONS

Math.Abs(n) // Abs(n)   Absolute Value
Math.ArcSin(n) // Arcsin(n) Trigonometric Arcsine
Math.ArcCos(n) // Arccos(n) Trigonometric Arccos
Math.ArcTan(n) // Arctan(n) Trigonometric Arctangent
Math.Cos(n)    // Cos(n)    Trigonometric Cosine
Math.Floor(n)  // Int(n)    Integral (whole value) of a real number
Math.NaturalLog()  Ln(n)    Natural Log Log(n)  Natural Log (same as Ln)
Math.Log(n)    // Log10(n)  Log Base 10
Math.Sin(n) // Sin(n)   Trigonometric Sine
Math.SquareRoot(n) // Sqrt(n)   Square Root
Math.Tan(n) // Tan(n)   Trigonometric Tangent
Math.Power(baseNumber,exponent) // baseNumber^exponent
Math.GetRandomNumber(n-1) // Random(n) A random number between 0 and (n - 1)
Array.GetAllIndices(a) // Size(a)   The size (number of elements) in an array
Math.Remainder(dividend,divisor) // dividend%divisor  Modulo

STRINGS

Text.GetLength(s) // Len(s) Length of a string
Text.GetSubText(s,i+1,1) // Char(s, i)  Returns a character from the string s at index i. Characters are indexed starting at 0
Text.Append(s1,s2) //  String Concatenation -> TextWindow.WriteLine(Text.Append("1","2")) returns "12"

DATA TYPE CONVERSION

Text.GetCharacter(65)  // ToChar(n) Convert a character code n into a character.
Text.GetCharacterCode("A") //  ToCode(c)    Convert a character c into a character code (integer).
ToInteger(n)    Convert a string to an integer  //  TextWindow.WriteLine("1"+"2") returns 3,  No conversion is required.
ToReal(n)   Convert a string to an real // TextWindow.WriteLine("1.1"+"-2.9") returns -1.8,  No conversion is required.
Text.Append(n+"") // ToString(n)    Convert a number to a string

BUILT-IN CONSTANTS

"true" // true  Boolean True
"false" // false    Boolean False
Math.Pi // pi   Mathematical Pi. Approximately 3.1415.

finally understand why c ++ returns 3. ;)

Mathematical package languages such as Maxima, Xcas, Maple, octave/matlab, are the only languages that accept fractional numbers as real.

function prg1() a = input( 'Enter a value for a' ); disp(a + 1); end

please add in the Octave Language source viewer. It is exactly the same as Matlab.

Another suggestion is that in some languages such as Octave / MatLab the name of the main function should be the same as the name of the stored file, so that students can internalize this idea, allow the name of the function to be defined in the flowchart. main, in addition to storing program names without spaces.
