  There are two primary uses for this statement.  First and foremost, it
  allows you to keep the SysOp informed of what the user does while using
  your PPL application.  Secondly, it can allow you to track information
  within your PPE while debugging.

  PRINT "Type QUIT to exit..."
  WAITFOR "QUIT",flag,60
  IF (!flag) LOG "User did not type QUIT",FALSE
  LOG "***EXITING PPE***",TRUE
