questions: no input file, and pascal programming

[Philip]

Hmm, that would spoil things.

reading this

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
