NAME
       pid - Retrieve process id(s)

SYNOPSIS
       ppiidd ?fileId?



DESCRIPTION
       If  the  fileId  argument  is  given then it should normally refer to a
       process pipeline created with the ooppeenn command.  In this case  the  ppiidd
       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 ppiidd returns the process identifier of the
       current  process.   All  process  identifiers  are  returned as decimal
       strings.
