An ordered map is a type of associative array that maps keys to values, maintaining an order to the keys. The concept is similar to an indexed file with a single variable length key and a single variable length data structure, either a simple string or a multi-member structure. ORDMAPM allows multiple key-value pairs with the same key, while ORDMAP does not.
