  every time an error occurs; or treat all errors as fatal
  errors, killing the interpreter. I strongly recommend
  "report once" as the default. But you can compile in a
  different default by changing the definition of
  ERR_DEFAULT_REPORT_MODE. In any case, the player can
  specify a report mode on the command line by typing "-Z 0"
