The scripts that you create in DIAdem are based on Visual Basic Script (VBS). The following topics cover the programming language VBS, from explanations about Data Types, the use of Variables, Constants, Operators, and Procedures, to the Definition of Classes and Using Objects.

General

Visual Basic (VB) is an object-oriented programming language developed by Microsoft and is used for creating applications and components. Visual Basic Script (VBS) is a script language derived from VB, which contains a subset of the VB functionality. VBS is an interpreter language.

VBS contains Control Structures, that is, commands for conditional statements, looping statements, numeric calculations, and for processing text. VBS supports the definition and use of variables and objects. You use commands to create processes that can be reproduced at any time. You save the processes in a text file with the extension .vbs. This enables you to change and to adjust these processes later.
