I tried to explain this before. ETHO often 'pipes' via a sequence of
viewers, with some manual input to move on to the next stage.
And I've done some experiments using <ET.Do> as a script, as described above:
 MarkPositionForViewer A
 Generate F1's output [to position A's viewer]
 MarkPositionForViewer A to be used as input for F2
 Generate F2's output, to the next Viewer
.......
 I can't remember details now: the mark & delete Viewer enabled removing
<pipe sections> that had finished their job, to make space for further
stages. The important fact is that ETHO already uses the paradigm:
 Function1 | Function2 |.....FunctionN
