When the AVM encounters certain unexpected error conditions, it throws an instance of the Progress.Lang.StopError class containing messages associated with the originating error, and raises the STOP condition.

Progress.Lang.StopError inherits common error handling abilities from Progress.Lang.ProError , which implements the Progress.Lang.Error interface. You can therefore catch this object in a CATCH block to trap error messages associated with the STOP condition.

You cannot inherit from this class.

Notes

  • To enable older behavior and prevent the AVM from throwing Progress.Lang.StopError objects, specify the Catch STOP ( -catchStop ) startup parameter with the value 0 ( -catchStop 0 ).
  • StopError objects are put on the SESSION:FIRST-OBJECT chain when they are caught by a CATCH block.
  • Uncaught StopError objects are automatically deleted by the AVM and removed from the SESSION:FIRST-OBJECT chain.
