PUBLIC INTEGER CopyPropertyValues (Object, Object)
Purpose: Copies property values from one object instance to another
Notes: Only copies properties with the same names. Property needs
to be PUBLIC GET on the source and PUBLIC SET on the
target. Ignores errors from GET and SET

Parameters:
poSourceObject Progress.Lang.Object
The object to copy property values from
poTargetObject Progress.Lang.Object
The object to copy property values to
Returns INTEGER
The number of copied property values

Parameters:
poClass Progress.Lang.Class
The reference to the class
pcMethodName CHARACTER
The name of the method(s) to return
Returns Progress.Reflect.Method
The Progress.Reflect.Method with the given name or ?
