How can I stop/halt script (1) , get prompt and execute script(2), once done return to script(1)?

I am looking to have "Press to Continue" button , while the control is at the Command Window prompt.

I could simply set the " keyboard " ,and once done set "return".

Example:

%=================================
for i=1:20; % Perform the following statements 20 times
      disp( ' M ' );
      keyboard; % Press "return" from prompt
 end 
%=====================================

When I halt/pause the "for loop " execution by " keyboard " command, I run a bunch of additional code or m.file script , my primer script using SOC to control equipment, etc....need to stay in last operation. Once done ( run script (2)) I would like to toggle a button to continue , basically to perform " return" function , callback of this button .

%=====================================
figH = figure;
uicontrol('Style', 'pushbutton', 'Callback', '????????(????)'); % ????????
for i=1:20; % Perform the following statements 20 times
      disp( ' M ' );
      % insted of ==>keyboard; 
   drawnow; % % 
   xxxxxx(figH); % % Halt and Set the prompt command window 
                                                           % Click Button =[send "return" ] ,insted of 
                                                           % typing in the prompt
 end 
%===============================================

Try adding a

return

command in your script. (Note: I would not expect this to work if it was a function you were running instead of a script.)
