FUNCTION GROUP

1. What is a function group?

GROUP OF ALL RELATED FUNCTIONS.

Function groups are containers for function modules. You cannot execute a function group. When you call an function module, the system loads the whole of its function group into the internal session of the calling program (if it has not already been loaded). For further information, refer to Organization of External Procedure Calls.

The following diagram shows the structure of a function group: The name of a function group can be up to 26 characters long. This is used by the system to create the components of the group (main program and corresponding include programs). When you create a function group or function module in the Function Builder , the main program and include programs are generated automatically.
