I want to run it for 5 times for different 'Current' so I manually change the value. So now I want to make it automatic

Amp=1;
while(exit)
    i=i+1;
    tic
    %reference       = S(i);
    %
    fprintf(eLOAD_instr, 'curr %2f',Amp)         % Setpoint to eLOAD
    pause(0.1)
    %
    %%Get Data from ELR9000
    % Setpoint, Current, Voltage, Power
    Data_eLOAD_string           = query(eLOAD_instr, 'curr?; measure:current?; measure:voltage?; measure:power?');
    % Write Data_string in vector of type struct
    Data_eLOAD_string_vec{i}    = Data_eLOAD_string;
    toc
    %
    while(toc < T_smpl)                % define Sampling time (0.1s)
         ;
    end
end
Set_pointStr = int2str(Amp)
save ( ['Test_',Set_pointStr,'_Amp' '.mat'], 'U_eLOAD','I_eLOAD')

in this code now I want to run it for 5 times for different 'Current' so I manually change the value. So now I want to make it automatic

Where are you setting the different current value? If it is Amp, You can define the values in array and then use a for loop iterating over the elements of the array.
