The action code makes reference to the actions dictionary, containing both the process code and the list of the parameters. In the window management, the value for these parameters is to be entered in the 2nd grid and thus for each action.
When the process triggered by the button or the menu does not open the window and only in this case, it is possible to reference the STD, SPE or SPV in the action code. For a window object, for example, the sub-program EXEBOUT or STATUT for the process SUBxxx, SPExxx or SPVxxx will then be executed ( xxx being the object code).
