The boolean editor uses a switch marking "Yes" to represent the true value and "No" to represent the value false value.

===== EGO Script =====

Boolean values can be denoted using several different representations:

^ Value ^ Representation ^
| True  | ''.yes'' \\ ''.true''  |
| False  | ''.no'' \\ ''.false''  |

By default, Dinamica EGO writes boolean values using the ''.yes''/''.no'' representation.
