Usage: ON [#|+|-|^|&|@]EXEC [-|^]<paramters> [action]
  This is activate whenever an EXEC'd process produces output
  to its standard output channel.  The process number is the
  number assigned by EXEC to the process (see HELP EXEC).  The
  parameters to this function are:
    $0	The process number that activated the ON
	If the EXEC was called with EXEC -name <process name>
	then $0 matches this name instead. This is very useful
	for keeping the processes separated out.
    $1-	The line of output to stdout
