Sorry I just saw your reply.
Can you please elaborate on ControlFile.ctl and what you meant by keystrokes?
What the exe file asks for upon opening is the path of the text file that it reads (where it is saved). In other words, it doesn't ask for variables or parameters.
I'm really desperate. Thank you again for your continued help.

Hello folks, I have an executable file (generated from a FORTRAN code)
that I need to run from matlab. Upon execution, it asks for the path of
the input file (C:\...Myprograms\sample.dat) and I have to enter it
manually but I want to do this programmatically, i.e., I want matlab to
get the input automatically and run the exe. I presume the function:
system (C:\...Myprograms\myexecutable.exe) is supposed to do the job but
for some reason it fails. Can anybody help me please? I'd be very grateful.

If it uses standard input, you should be able to use command line

redirection as part of the command string you submit...

Thank you. What I put in the myprogram.exe when I run it from DOS is this:
and it works perfectly (it doesn't ask for the number of data and the name of the output file). I followed what you said and ran the code:

system('C:/Mysoftware/Myprogram.exe < C:/Mysoftware/for005.dat');
but it doesn't work. In the command window I get:
Enter the input file name:
Unable to open this file. Try again

Is there anything wrong with my code? Thanks afresh.
