Progress.Lang.ProError is the super class for all ABL
built-in and user-defined classes that represent errors in the ABL structured error handling
model. You cannot directly inherit from this class. Instead, the immediate subclasses of
this class represent the two major types of classes in ABL:
-
Progress.Lang.SysErrorrepresents any error generated by the AVM. -
Progress.Lang.AppErrorrepresents any error your application defines.
Progress.Lang.ProError inherits from Progress.Lang.Object and therefore inherits all the common
methods and properties needed for managing user-defined objects in ABL. It also implements
the Progress.Lang.Error interface which provides all the
properties and methods relevant for an error object.
Specifically, this class provides the functionality to retrieve error messages, error numbers, and the contents of the error call stack.

Notes

Progress.Lang.AppError objects using garbage collection.
