hi everyone, what is meaning of this part of program?(CAN YOU WRİTE ANY COMMENT(S))

global nfile Qamp_mv Ramp_mv Samp_mv Tamp_mv P_1 Pamp_mv A flag c

                                if flag==4

                                set(handles.q,'string',['Q=' num2str(Qamp_mv)])
                                set(handles.p,'string',['P=' num2str(Pamp_mv)])
                                set(handles.r,'string',['R=' num2str(Ramp_mv)])
                                set(handles.s,'string',['S=' num2str(Samp_mv)])
                                set(handles.t,'string',['T=' num2str(Tamp_mv)])
                                set(handles.textll,'string',['PERSON HEALT:-' P_1])

                            else
                                errordlg('Calculate values/apply wavelet')
                            end

 global nfile Qamp_mv Ramp_mv Samp_mv Tamp_mv P_1 Pamp_mv A flag c  % Define global variables.

   if flag==4    % Condition if flag==4
%%Setting handles q p r s t assigns the specified value of the handles  to the specified property Q P 
       set(handles.q,'string',['Q=' num2str(Qamp_mv)])
       set(handles.p,'string',['P=' num2str(Pamp_mv)])
           set(handles.r,'string',['R=' num2str(Ramp_mv)])
         set(handles.s,'string',['S=' num2str(Samp_mv)])
   set(handles.t,'string',['T=' num2str(Tamp_mv)])
            set(handles.textll,'string',['PERSON HEALT:-' P_1])
                            else
       errordlg('Calculate values/apply wavelet')  % Create error dialog box 
                            end
