The various itemid are actually structures, but seem to have only one component, the id. The following code snippet (from memory) shows how it works...

declare

    myformid formmodule;
    saved_id integer;
begin

   myformid := find_form(:system.current_form);    saved_id := myformid.id;

/* now save 'saved_id' into a global, parameter, or whatever... */

end;

/* To use the saved value, just reverse...*/

declare

    myformid formmodule;
begin

   myformid.id := :parameter.saved_id; /* declared as a number */    go_form(my_formid);
end;
