How to answer a call for an input from the script?

So I used the system('run.bat') in my script to run a series of commands that will ask certain questions. I want to code the answers to those questions in my script such that I dont have to manually answer them in MATLAB's command window. Is there a way to do this?

per definition of the system cmd there will be no return value until the execution was finished

status = system(command) calls the operating system to execute the specified command. The operation waits for the command to finish execution before returning the exit status of the command to the status variable.

so I think the system cmd is not the way to solve your problem

Thats what I guessed as well. I tried researching few possibilities but failed in all directions. If you have any tips or somewhere to look further let me know.

I know if you run system('MyApp.exe') and MyApp.exe asks for your input and you key in three letters 'abc',

then you can create a text file, e.g. input.txt which contains the text 'abc' without the single quotes,

then you can run system('MyApp.exe < input.txt') which will not require you to type in anymore.

This method have helped many in this forum.

Try this with your 'run.bat'. I am not sure if run.bat calls many App.exe, whether you can combine all the inputs into one text file.
