X3 Basic Syntax

Print Program:

# Function definition for printing numbers
FUN printNumbers(start, end)
    # Loop from start to end
    FOR i = start TO end THEN
        # Print the value of i
        PRINT(i)
    END
END

# Main program
# Call the printNumbers function to print numbers from 1 to 10
printNumbers(1, 10)

Explanation:

  1. Identifiers:

    • printNumbers: Function name.

    • start, end, i: Variable names.

  2. Reserved Words:

    • FUN: Used to define a function.

    • FOR, TO, THEN, END: Keywords used for loop control.

    • PRINT: Keyword for outputting a value.

  3. Lines and Indentation:

    • Each line represents a statement or a block of code.

    • Indentation is used to denote blocks of code within functions or loops.

  4. Comments:

    • Comments are preceded by the # symbol.

    • They provide explanations or documentation for the code.

Explanation of the Code:

  • The code defines a function named printNumbers that takes two parameters: start and end.

  • Inside the function, there's a FOR loop that iterates from start to end, printing each value of i.

  • The main program calls the printNumbers function with arguments 1 and 10, causing it to print numbers from 1 to 10.

Additional Notes:

  • Data Types: The provided pseudocode doesn't explicitly mention data types. In X3, you would need to define the data types for variables and function parameters.

  • Execution: In X3, after defining the function and the main program, the code would be executed sequentially, starting from the main program's entry point.

This breakdown should give you a clearer understanding of how the given pseudocode translates into a print program in your X3 programming language.
