SYNOPSIS
pid ?fileId?
_________________________________________________________________
DESCRIPTION
If the fileId argument is given then it should normally
refer to a process pipeline created with the open command.
In this case the pid command will return a list whose
elements are the process identifiers of all the processes in
the pipeline, in order. The list will be empty if fileId
refers to an open file that isn't a process pipeline. If no
fileId argument is given then pid returns the process
identifier of the current process. All process identifiers
are returned as decimal strings.
KEYWORDS
file, pipeline, process identifier
