Here, the ``4'' and ``A'' commands should be executed first. Then, execute the ``D'' to examine all the windows. Finally, after all the windows have been examined, the data must be registered in a final MIDAS table with the command REGISTER/ROMAFOT. This command assigns identification number to the objects corresponding to the group identification: the first component will have identification N*100+1, the second N*100+2, etc, where N is the group identification number.
