[CMS-PIPELINES] APPEND Connector

[Paul Gilmartin]

My (only) input is connected to a TCPCLIENT stage.

I'd like to output some prefix data, then shunt the TCP to output:

 'output' dataline
 'callpipe *.input: | *.output:'

... works well enough, but I thought I might save a command:

 'callpipe var dataline | append *.input: | *.output:'

... the result is unpredictable: the amount of data output
from the same input varies.  Why?  Is there a better way of
doing this?

Thanks,
gil
