The "stack" stage will read all from the stack when you let it. When your pipeline decides to read only 1 line from the stack, the rest remains there for next time. The remainder of the pipeline propagates end-of-file backward, so tells the stages earlier in the pipeline to give up when they can. Along the same lines, when you use just the first 10 records of a file, CMS Pipelines will not read the entire file but will stop after the first bit. Indeed, "PIPE stack | hole" will consume all records from the stack. At that point "stack" will report end-of-file and "hole" will terminate as well. Rob
