DEFINE VARIABLE oSettingsService AS Consultingwerk.Framework.ISettingsService NO-UNDO .
oSettingsService = {Consultingwerk/get-service.i Consultingwerk.Framework.ISettingsService} . |
The get-service.i Include file uses the Progress.Lang.Class:GetClass() method up to OpenEdge 11.3 and the GET-CLASS function from OpenEdge 11.4 on. For this reason it is required to pass the full type name (not relying on any USING statement) up to OpenEdge 11.3.
