procedure Define(
    const AWord: String; 
    AResults: TIdDefinitions; 
    const AGetAll: Boolean = True
); overload;

Define is an overloaded method used to implement the DICT DEFINE command. Define performs a lookup for the definition of the specified word in the databases on the DICT server. 

AWord indicates the word to lookup in the databases on the DICT server. 

AResults is the TIdDefinitions instance used to store definitions retrieved from the DICT server. 

AGetAll indicates that all word matches in all databases will be included in the definitions returned to the client. When AGetAll contains False, a single match from all databases is returned. 

Define will normally result in the following status codes being returned to the client: 

Definitions returned with response code 151 are captured and stored in the AResults.
