Hmm, that would spoil things.

the opinion there is that sending control-Z is just a signal from the
keyboard to the shell which the shell uses to cut the flow to the
application listening on stdin, it doesn't actually send control-z to
the app.
in other words I need to flush and close the input side of the pipe, but
not the output side or won't collect the program output.
I was hoping that tprocess.CloseInput might acheive that but it doesn't
seem to cause gpg to stop listening for input.
Anyone got any ideas?
thanks, Philip

Under DOS, redirecting from the standard output of A to the standard
input of B meant the contents were stored in a temporary file somewhere,

Windows still doesn't do that when running those at the command line.

I have come to the conclusion that you can pipe stuff to gpg from inside
dos window, but that if you try to pipe stuff directly from the pascal
program it fails.
I actually got my program to work by piping to cmd.exe with "echo Mary
had a little lamb|gpg" inside the stream, which sort of proves that I
know how to program a pipe.
Example code is at
http://www.christiantena.net/freepascalgpgexample.zip
you can look at this code by installing lazarus, unziping the above file
into a folder, and then from lazarus do project/open project and point
it at the lpi file in the folder
hit F9 to compile it
This feels a bit like a bug in gpg to me...

So far I have figured out that on windows if I enter the command
gpg -eat -r [recipient key]
I get a prompt on the console
If I then type a message, followed by <enter> control-Z <enter>
then gpg will encrypt the message and dump the pgp text to the screen,
or to a file if I used the -o [filename] option.
However on linux control-Z just terminates the program (no pgp text)
Does anyone know the official, correct console way to get pgp to
terminate and output the encrypted text from console?
I'm amazed that it just doesn't seem to be documented anywhere.
Take a look at the ASCII table (man ascii :). There is ^D (EOT - end of
transmission) for this. This is used by all systems I'm aware of but
window$. Don't know why they use something diffrent, maybe just to be
diffrent and break the standard.
