How to generate output from .exe program via java robot keypress using matlab

hi sir, i want to run an external .exe program from matlab and want to generate output file from that program automatically. The .exe program generates output upon pressing F7 key. so i used java.awt.robot for pressing F7 key.

But the problem is that it doesn't press key when .nec is open it presses key after .exe program is closed. How can i make it able? thanks in advance

function APIrobot()
clear all; close all; clc;

import java.awt.Robot;
import java.awt.event.*;

robot = java.awt.Robot();
robot.delay(2000);
!phi150arm.nec      %this is the external .exe program from which i want to generate output
    robot.keyPress(KeyEvent.VK_F7);
    robot.keyRelease(KeyEvent.VK_F7);
end

Several issues here (and I don't know how to solve any of them otomh, unfortunately...)

Just for starters--

1. MATLAB is single-threaded w/o parallel TB so you're correct that system starting the .exe will wait for it unless you use the trailing "&" ampersand to start a new session and go on..that done, the next problem is
2. Somehow the keypress has to be directed to the process it's intended for -- how that's done I dunno; one presumes there's something in the package that allows such.

Just saw the following https://www.mathworks.com/matlabcentral/fileexchange/29594-textinject

Don't know if that could be munged/used for purpose or not...
