or

X3 programming language, the keyword "or" serves as a logical operator. Let's delve deeper into its functionality and usage:

Functionality:

The "or" keyword is used to combine two logical conditions. It evaluates to true if at least one of the conditions is true. If both conditions are false, the overall expression evaluates to false.

Usage:

var x = 5
var y = 10

# Using 'or' in an 'if' statement
if x > 0 or y < 5 then
    show("At least one condition is true.")
end

Explanation:

• In this example, the "if" statement checks if either x is greater than 0 or y is less than 5.

• If either of these conditions is true, the statement inside the "if" block will be executed.

Example:

var isWeekend = false
var isHoliday = true

# Using 'or' in a compound condition
if isWeekend or isHoliday then
    show("It's a weekend or a holiday!")
end

Explanation:

• Here, the "if" statement checks if isWeekend is true or isHoliday is true.

• If either variable is true (or both), the statement inside the "if" block will be executed.

Short-circuit Evaluation:

In many programming languages, including X3, "or" follows short-circuit evaluation. If the first condition is true, the second condition won't be evaluated because the overall expression will already be true.

Example:

var x = 5
var y = 10

if x > 0 or y / x > 3 then
    show("At least one condition is true.")
end

Explanation:

• In this example, if x is greater than 0, the expression will be true without needing to evaluate y / x > 3. Thus, the division operation won't occur if x > 0 is true.

By incorporating the "or" keyword as a logical operator in your X3 language, you provide users with the ability to express compound conditions in their programs, allowing for more flexible control flow.
