how to emulate pressing the Enter key

System: Windows 7 64 bit. Interface: cmd.exe.

I need to run an executable in batch. When run in interactive mode, the executable asks for a sequence of commands (each one of course followed by the Enter key) and finally it asks you to press the Enter key to continue (and finish). This last step is blocking me. I managed to write the following:

mycode.exe < batch.txt

where the file batch.txt has the following content.

bar.out
28
foo.in
summary.out

The four lines contain the correct commands mycode.exe. The problem is that I don't know how to send the "Enter" command to mycode.exe...is there a way?

EDIT: maybe I'm not using the right words. I'm not a programmer nor a computer scientist. I'll try with a practical example: if I open a cmd prompt and write (followed by Enter)

D:\test> mycode.exe

I get

Enter output file name:

I write

bar.out

Then I get a list of options among which to choose, and the prompt:

Enter option from menu:

I enter

28

I get

Enter input file name:

I enter

foo.in

I get

Enter summary file:

I enter

summary.out

Then the code sends a long output to screen, and finally it writes:

Press ENTER to continue

If, instead than running it from the command line, I use

mycode.exe < batch.txt

I get a Fortran error, so I was thinking that maybe I would need to include the equivalent of pressing the ENTER key, inside my file batch.txt.

Since the program appears to read from the standard input stream, adding a final blank line to batch.txt should do the trick. If it doesn't, then that last prompt is not using standard input, and you'll have to resort to such third-party trickery as SENDKEYS or KEYSTACK.
