Until Break Statement

Until Break Statement

Until break statements are used to conditionally execute a block of code until a break is encountered

until break {
    // ...
}

Execution Condition

The code inside the block will be executed or be re-executed until a break is encountered

Usage example

import basics

func main {
    value int = 0
    
    until break {
        value = scanInt("Enter a value that isn't zero: ")
        if value != 0, break
    }
    
    print("You entered " + value)
}

Break and Continue

Both break and continue apply to until break statements

Loop Labels

Loop labels can be used for until break loops by specifying a name for the loop label after until break

name String = ""
until break waiting_for_valid_name {
    name = scan("Enter your name: ")
    
    if isInvalid(name) {
        print("Please enter a valid name!")
    } else {
        break waiting_for_valid_name
    }
}
