Conditions

With a condition statement you can execute a block of code if an expression evaluates as true.

If

The if statement lets you compare two values, when the condition is true then the code between if...end will be executed.

proc main()
    number n = 5

    if n == 5
        printS("Five")
    end
end

Booleans

When there is no condition specified in an if statement then the value is compared to 0. The condition evaluates as true when the value is not equal to 0.

proc main()
    number b

    if b
        printN("True")
    end
end

Not

It's also possible to execute a block if an expression evaluates to false, this can be done with the not keyword.

proc main()
    number b

    if not b
        printN("False")
    end
end

Else

With the else statement you can execute a block of code if the if condition is false.

proc main()
    number n

    if n == 4
        printS("Four")
    else
        printN("Not four")
    end
end

Logical operators

With a logical operator you can compare multiple values, there are two logical operators: and and or.

proc main()
    number a
    number b

    ; A and example...
    if a == 5 and b == 5
        printS("A and B are five")
    end

    ; A or example
    if a == 5 or b == 5
        printS("A or B is five")
    end
end

Select

With a select you can compare a value to one or more values to select a block of code to execute. The code is executed until another case or the end of the select block is reached.

proc printMessage(number n)
    number n

    select n
        case 1:
            printS("one")

        case 2:
            printS("two")

        case 3:
            printS("three")

    end
end

proc main()
    printMessage(2)
end

Assembly operator commands

The operator is the oposite of the condition, if the condition evaluates to true then the code is skipped with a jump.

Condition	Sign	Operator
Not equal	!=	je
Equal	==	jne
Greater or equal	>=	jl
Less or equal	<=	jg
Greater	>	jle
Less	<	jge
