Beyond Core LotusScript

IBM software environments
IBM software provides the environment in which you create, debug, and run LotusScript modules. IBM software applications that work with LotusScript supply their own application programming interface (API), which lets you use product functionality and create and manipulate product objects from within a LotusScript program. A IBM software API is effectively an extension to the LotusScript language that is available when you are running that product.

Interacting with the user
IBM products lend themselves to building interactive applications, applications that incorporate user input and prompt the user to perform particular tasks. While each individual IBM software application provides its own user interface for interacting with scripts, LotusScript supplies some fundamental tools that you can use with any IBM software.

Interacting with other programs
LotusScript provides a number of functions and statements that you can use to interact with other programs and the operating system. You can also use Object Linking and Embedding (OLE) to incorporate functionality and data from other Windows applications into your LotusScript applications.

Calling external C language functions
LotusScript allows you to call external C language functions. You implement external C functions inside a named library module that generally contains several C functions. With Windows, this is a Dynamic Link Library (DLL). All Windows users have access to the libraries in the Windows application programming interface (API).

LS2J: Connecting with Java
Using LotusScript and LS2J, you can access Java classes, giving you a powerful cross-platform extension to LotusScript. Developers can access Java in LotusScript programs as a set of predefined LotusScript objects. This set of objects allow LotusScript to use already created Java classes that are available in script libraries or found using the classpath.
