# Command: handleerror

Name:

    handleerror - Default error handler

Description:

      handleerror is the default error handler.
      It issues error messages according to the
      state of the errordict.
      The command that caused the error is left at the
      top of the dicitonary stack.

      An error is raised by the command
      /func /error raiseerror

      The flag newerror helps to distinguish between interrupts caused
      by call of stop and interrupts raised by raiseerror.
      It also helps to find errors in the handler itself. This is
      why it should be re-set to false at the very end of the handler!

      Examples:  To catch errors from an unknown function f,
      one can write:

      {f} stopped {handleerror} if
