}Macros aren't useful for this; they're useful when you want to do a
}repetitive operation within a single ftp session.  You want a script like:
}
}#!/bin/sh
}ftp hostname <<END
}username
}password
}bell
}ascii
}cd /foo/bar
}get it
}quit
}END
}
}I don't know how secure this is, though.  I'm not sure what it will do if
}the user types ctl-C in the middle of it.

Write an Expect script.  You can check for errors, prevent ^C from
interrupting it, and hide any disgusting parts of the ftp dialogue at
the same time.
