LSPS comes with many useful functions in its Standard Library as well as other libraries. However, if no appropriate function is available, you can implement your own functions either in the Expression Language or in Java:

Functions in the Expression Language are created directly in the function definition file.
Functions with Java implementation require that the implementation is integrated in the Application User Interface. Therefore, you will need Designer and LSPS Repository installed and set up so you can generate and modify the LSPS application. Detailed instructions are available here.

Calling a Function

Functions are called by their name followed by their parameters:

<FUNCTION_NAME>(<FUNCTION_PARAM1>, <FUNCTION_PARAM2>)
