Well, I decided to add a COUNT | VAR ... stage, which takes ADDPIPE
and SHORT out of consideration. I suppose with some SPECS I could
have avoided VAR. I'm too naive.
But another question: my pipeline writes the data body to *.OUTPUT.0:
and messages I generate to *.OUTPUT.2:. The caller may connect
either or both of these to CONSOLE. If both, I'd like the summary
to appear after the body. This seems to be unpredictable. But,
empirically, if I:
select output 0
sever output
select output 2
output 'Count was' whatever 'characters.'
Is this the best way to enforce this? Or is it just silly to try
to control the order in which parallel stages operate?
Thanks,
