This session will introduce a new component (which is in itself a revision of older ones.) The component implements an abstract data structure know as key-value pairs. This component can be used as an Object Tools, XML Bags, or Variables-on-Demand alternative. A novel syntax has been developed for the component allowing the retrieval of values by a totally text-based mechanism. This component combined with Dynamic Variables (introduced in v12) can dramatically decrease the memory footprint of your 4D app. Other techniques will also be demonstrated such as anonymous process dictionaries with automatic garbage collection, preferences and xml export.
