'and' Operator in X3

"and" is a keyword in your X3 language, it would likely be used as a logical operator to perform logical conjunction between two conditions. Here's how you can integrate it into your language:

Logical AND Operator:

The "AND" keyword can be used to combine two logical conditions, and it evaluates to true only if both conditions are true.

Example:

var x = 5
var y = 10
IF x > 0 and y < 20 THEN
    show("Both conditions are true.")
end

In this example, the code inside the "IF" statement will be executed only if both conditions (x > 0 and y < 20) are true.

Precedence and Grouping:

You may want to define the precedence of the "AND" operator and allow users to use parentheses for grouping logical expressions.

Example:

var x = 5
var y = 10
var z = 15
if (x > 0 and y < 20) and z == 15 THEN
    show(All conditions are true.")
end

Short-circuit Evaluation:

You might consider implementing short-circuit evaluation for the "AND" operator, meaning that if the first condition is false, the second condition won't even be evaluated.

Example:

var x = 5
var y = 25
if x > 10 and y / x > 3 then
    show("This won't be executed due to short-circuit evaluation.")
end

In this example, since x > 10 is false, y / x > 3 won't be evaluated.

By incorporating the "and" keyword as a logical operator in your X3 language, you provide users with the ability to express complex logical conditions in their programs.
