Setting session variables with front-end functions

A set of front-end functions allows you to dynamically set and get session variables from within your Genero application.

Reminder of Genero Front-End call syntax

ui.Interface.frontCall( module, function, parameter-list,
returning-list )

Table 1. getvar and setvar front-end functions
