Target Audience
This manual is aimed at developers who already have a working knowledge of their development environment and
their chosen reader platform. We make the following assumptions.
• C/C++ API - We assume you have a working knowledge of the C++ language.
• .NET - We assume that you know how to develop for .NET and understand .NET concepts like static classes,
IDisposable and IEnumerable.
• ActiveX - We assume that you know how to develop with ActiveX.
• Java - We assume a working knowledge of the Java language.
• JavaScript - We assume a working knowledge of Javascript.
• OPOS and JavaPOS - We assume knowledge of the UPOS (OPOS and JavaPOS) specification version 1.13 and
familiarity with Point of Sale applications and developing with OPOS/JavaPOS.
