Initializer

function setValue(const newValue: Variant; const makeDirty: boolean = true): Variant; override;

Set the value of the option. This method overrides the behavior inherited from ACommandLineOption.setValue; it attempts to cast newValue to a numeric value. If that succeeds, the new value is set; otherwise it is ignored and an exception is thrown. Returns The previous value of ACommandLineNumber.value. Exceptions raised AnOptionValueError in the event that the attempt to cast newValue to a numeric value fails.
