else

In your X3 programming language, the "else" keyword is used in conjunction with an "if" statement to specify a block of code to be executed if the condition in the "if" statement is false. Here's how you would use the "else" keyword in your X3 language:

Basic Usage:

var x = 10

# Using 'if' with 'else'
if x > 10 then
    show("x is greater than 10.")
else
    show("x is not greater than 10.")
end

Explanation:

• In this example, the "if" statement checks if the variable x is greater than 10.

• If the condition x > 10 evaluates to true, the code inside the "if" block executes. If not, the code inside the "else" block executes.

Elif Clause:

var x = 10

# Using 'if' with 'elif' and 'else'
if x > 10 then
    show("x is greater than 10.")
elif x == 10 then
    show("x is equal to 10.")
else
    show("x is less than 10.")
end

Explanation:

• In this example, if the condition x > 10 is false, the "elif" statement checks if x is equal to 10.

• If x is neither greater than 10 nor equal to 10, the code inside the "else" block will be executed.

Multiple Elif Clauses:

var x = 5

# Using multiple 'elif' clauses with 'else'
if x > 5 then
    show("x is greater than 5.")
elif x == 5 then
    show("x is equal to 5.")
elif x < 5 then
    show("x is less than 5.")
else
    show("This should never happen.")
end

Explanation:

• If none of the conditions in the "if" and "elif" clauses evaluate to true, the code inside the "else" block will be executed.

Nesting Else Statements:

var x = 10

# Nesting 'if' with 'else'
if x > 5 then
    show("x is greater than 5.")
else
    if x == 5 then
        show("x is equal to 5.")
    else
        show("x is less than 5.")
    end
end

Explanation:

• In this example, an "if" statement is nested within the "else" block. This nested "if-else" structure allows for more complex conditional logic.

By incorporating the "else" keyword in your X3 language, you provide users with the ability to handle alternative cases when conditions are not met, enabling more comprehensive control flow in their programs.
