Usage consideration

Function requirements

• Keywords must be unique.
• Keywords are not case sensitive.

Maps vs. dictionaries

While similar to a dictionary, which uses curly braces {}, the values stored in a map are not wrapped in variants. This makes it much easier to get values back out of maps by indexing, without having to worry about type casting. There are no advantages to using dictionaries; prefer using maps over dictionaries where possible.

Casting a map

• A map can be cast to a dictionary, CDT, record, or text.
• A dictionary, CDT, or record can be cast to a map.
