… but I found the problem. I don't know how to pass the list from one subshell to the other.

% { echo pick; echo merge; a=12 } | { echo +$a+; while read line; do echo $line; done; } ++ pick merge

The only idea I have is a file. Do you have a better idea?

% { echo pick; echo merge; a=12 } >/tmp/tmp; \
  { echo +$a+; while read line; do echo $line; done; } < /tmp/tmp
+12+
pick
merge

Bye, Jörg.
