end

In your X3 programming language, the "end" keyword is used to mark the end of a code block. It is commonly used to close control flow statements such as "if", "for", "while", and function definitions. Here's how you would typically use the "end" keyword in your X3 language:

Usage with "if" Statement:

var x = 10

# Using 'end' to mark the end of the 'if' block
if x > 5 then
    show("x is greater than 5.")
end

Explanation:

• In this example, the "end" keyword marks the end of the code block that is executed if the condition (x > 5) in the "if" statement is true.

• It signifies the termination of the block associated with the "if" statement.

Usage with "for" Loop:

# Using 'end' to mark the end of the 'for' loop block
for var i = 1 to 5 then
    show(i)
end

Explanation:

• Similarly, in a "for" loop, the "end" keyword marks the end of the code block to be executed in each iteration.

• It signifies the termination of the block associated with the "for" loop.

Function Definition:

# Using 'end' to mark the end of a function definition
fun greet(name)
    show("Hello, {name}!")
end

Explanation:

• In this example, the "end" keyword marks the end of the function definition for the "greet" function.

• It denotes the termination of the block of code defining the function.

Nested Control Flow Statements:

# Using 'end' to mark the end of nested control flow statements
if condition1 then
    if condition2 then
        show("Both conditions are true.")
    end
end

Explanation:

• In nested control flow statements, each "end" keyword corresponds to the termination of the innermost block it closes.

• It's essential to ensure proper indentation and matching of "end" keywords to maintain code clarity and correctness.

By incorporating the "end" keyword in your X3 language, you provide users with a clear and explicit way to delineate the end of code blocks associated with various control flow structures and function definitions, contributing to code readability and maintainability.
