Abstract This redbook describes how to work with LotusScript, a BASIC-like, object-oriented programming language that comes as part of Lotus Notes Release 4 and other Lotus products. The introductory chapter compares LotusScript and Visual Basic. Other chapters cover Lotus Notes as an OLE 2 automation server and OLE 2 automation client. A description of the LotusScript Notes classes is also provided. The redbook focuses on how to convert HiTest applications, and how to access the major Notes elements using: The HiTest Basic API Notes classes in Visual Basic through OLE automation LotusScript in Notes. This redbook was written for Visual Basic programmers who want to learn about the features of LotusScript, and who are planning to migrate their HiTest applications. Some knowledge of the HiTest Basic API and of Visual Basic is assumed. iii
