Simultaneous write and read with different programs.

[pecan204]

Is it possible to write to a file with one program and read that same file instantaneously with another program?

Suppose I wanted to simulate data being written from a control system computer and the second program would read that data reduce itas soon as it is written.

If this can't be done with fortran are there any alternatives?

Thanks for any comments

It can be done, though a file isn't the best way of doing that, as there can be synchronization problems and the need to periodically "flush" the output.

Windows has a number of mechanisms for sending and receiving data between programs - a pipe would probably be the most appropriate for you. You can read about these in the "Platform SDK" part of the Visual Fortran (or MSDN) documentation.

The classic starter is this MSDN article. It's in C, of course, but I did recommend it few times here so someone should have a Fortran translation. Anyone?
