NAME
       pid - Retrieve process id(s)

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.
