=== [[MUMPS]] ===

In [[MUMPS]] every array is an associative array. The built-in, language-level, direct support for associative arrays

applies to private, process-specific arrays stored in memory called "locals" as well as to the permanent, shared, global arrays stored on disk which are available concurrently byto multiple jobs. The name for globals is preceded by the circumflex "^" to distinguish itthem from local variable namesvariables.

SET ^phonebook("Sally Smart")="555-9999" ;; storing permanent data

SET phonebook("John Doe")="555-1212" ;; storing temporary data

SET phonebook("J. Random Hacker")="553-1337" ;; storing temporary data

MERGE ^phonebook=phonebook ;; copying temporary data into permanent data

To accessAccessing the value of an element, simply requires using the name with the subscript:

WRITE "Phone Number :",^phonebook("Sally Smart"),!
