On the popen problem, when I said:
"If I delete every "%c" and ",10" from the code above, the user DOES see the
response appear in his/her Mosaic browser, but of course, the ftp command
fails."
I meant every %c in the fprintf commands. The %c's in the printf commands
stay. So it is only the newlines in the fprintf commands, that get sent to
ftp, that fail.
