I work under Linux, and run programs using shell scripts, with data
read directly out of the script, by using something like this

ifort bla.f90
../a.out << eoi
<data1>
<data2>
eoi

A colleague (who doesn't frequent news groups) works under Windows
and wants to do something similar. He already has a compiled
program, e.g. bla.exe and wants to know how to make the batch
process read data directly from the batch file, as my script
does. How is that done?

Under Windows the executable is usually given the name of the first
Fortran file, so it would be

bla <eoi

which would read data requested from the default terminal (usually unit 5;
I always use the * as my default terminal). To save default screen output,
try

bla <eoi >my-output.txt

We normally make sure that our files have an extension, so would have

bla <eoi.txt >my-output.txt

You would need to make sure that bla was compiled for command-line prompt
(Windows console) NOT QuickWin or Windows GUI.

You can - at the very least - do that as follows:
- Put the data in a separate file, say "input"
- Then run the program like this:

   program.exe < input

This will certainly work, but alternatives you might try is
a pipe:

   cat input |program.exe

I do not think the <<label ... label trick works with Windows
batch files. (But then: MinGW provides a bash for Windows and
there is also a winbash ...)
