JSON functionality in Lycia

JSON (JavaScript Object Notation) is a lightweight format for data interchange. It is a text format that is completely language independent but uses conventions that are familiar to C programmers.

Lycia incorporates JSON functionality in order to give 4gl developers new tools for data interchange and help them to create modern and user-friendly applications.

This chapter describes only the JSON functionality embedded in Lycia and executable from the 4gl code.

For greater details on JSON, refer to the original JSON documentation.
