the act of error processing involves:

  • detecting the error
  • ignoring it
  • aborting the procedure or program
  • noting the error
  • dealing with it, such as looking for and trying an alternate approach to the service where the error occurred
  • trying to fix the error. this could be regarded as an optional intermediate step.
