Hi,

I'm trying to put a Tk front-end onto a program I've been given
which reads from stdin.

Looking at the manual, it seems that I could do this with exec,
getting the prgram to read from a socket and writing the arguments to
that socket. However, I'm on Windows, and the manual says that reading/
writing from/to a socket doesn't work on Windows.

Is there a mechanism that DOES work, other then writing a
temporary file, which I can see would work, but seems inelegant.

TIA
Alan

Yes, there is:

exec yourprogram << $value

where $value is the value of a variable filled with the
input for the program.

BTW sockets work just as they are supposed to.

You may find http://wiki.tcl.tk/3359 of some interest
as well (more general than just Fortran programs :))

You may also want to look at the open command with the pipe ("|") option.
