# Builtins.Invalid\_Value(3kaya)

Invalid or uninitialised value

## NAME

Builtins::Invalid\_Value - Invalid or uninitialised value

## SYNOPSIS

**Builtins::Invalid\_Value(** **)**

## DESCRIPTION

This Exception is usually thrown when operations are carried out on an uninitialised value, for example:

-

   xs = \[\];\
    xs\[0\] = "Hello";\
    if (xs\[0\] == xs\[300\]) {\
        // Invalid\_Value thrown\
    }

It may also be thrown by **Builtins.unmarshal (3kaya)** if the marshalled String is corrupt.
