A kind of array (hashtable)

Hello, In some language (like Java, C#, ...) you can find a hashtable. I execute query, this query return some records, each records are composed by 2 fields. I'd like to put these records in a 2 dimensions array (or something like that) and find easily the records I want. An example, the query return (field1/field2): mytext1 / "text for my text 1" mytext2 / "text for my text 2" mytext3 / "text for my text 3" mytext4 / "text for my text 4" I'd like to put that in an array, but not find the text by myarray[2], myarray[4] but by myarray['mytext2'], ['mytext2'] have to return "text for my text 2" Possible to do that ? Bye
