This function provides a string with the standard parameters forwarded from DataView to Action Userexits. This does not change during the runtime of the LogiView procedure; even if a new widget is opened in LogiView or another data record is selected or edited. When calling mask userexits which are forwarded a standard parameter ('lgv_edt_act', 'lgv_pre_act' and 'lgv_post_act'), this function returns a string with the forwarded parameter. This string is a combination of the work mode (see function mode()) and the current line (see function row() ). |
