Basics of i

Variables

n = 3
s = "string"

Concepts (aka Functions)

concept add(a,b) {
    return a+b
}
concept printchars(s) {
    for char in s
        print(char)
    end
}
concept hello() {
    return "hello"
}

If statements

If statements take numeric values, 0 is false, anything else is true.

if expression
    print("expression is true!")
else if condition
    print("expression is false...")
    print("but condition is true!")
else
    print("expression and condition are false...")
end

Loops

The loop statement loops over the enclosed block of code an unspecified amount of times, it's up to you to break out of the loop when you need to.

loop {
    if leaving
        break
    end
}

For Loop

The for loop is more useful as it strictly specifies how many times the loop will run.

for element in array
    print(element)
    if bad(element)
        delete() //--This deletes the element (does not preserve order)
    end
end

for value in array
    print(i, ":", value)
end

for each 0 to 10
    print(i)
end

for each in array
    print(i)
end

Errors

The errors block will run if there has been an error.

n = number("abc")
errors {
    print("Could not convert abc to a number!")
}
