35 Input and output in {\eclipse} is done via communication channels
43 or for both input and output (\defnotion{update mode}\index{mode!update}).
56 This is by default the same as user_input and stdin, but can be redirected.
60 This is by default the same as user_output and stdout, but can be redirected.
62 Output for error messages and all messages about exceptional states.
63 This is by default the same as user_error and stderr, but can be redirected.
66 This is by default the same as user_output and stdout, but can be redirected.
70 This is by default the same as user_output and stdout, but can be redirected.
107 In a stand-alone {\eclipse} stdin, stdout and stderr are connected
109 In an embedded {\eclipse}, the meaning of stdin, stdout and
135 identical to \notation{stdin} and \notation{stdout},
