Microsoft Script Debugger for Internet Explorer

Microsoft® Script Debugger for Internet Explorer 4.0 is a debugging environment that extends Microsoft Internet Explorer 4.0 and Microsoft Internet Information Server (IIS) by allowing Web developers to browse, edit, and debug .htm and .asp pages that contain Visual Basic Scripting Edition (VBScript) or JScript (compatible with ECMA 262 language specification). The Microsoft Script Debugger gives developers a seamless way to combine HTML and script development. Developers can also use the debugger to test programs written in Sun Microsystems' JavaScript. They can then run the programs using the Microsoft Java Virtual Machine (VM), and to debug scripts for any scripting language engine that supports Microsoft ActiveX® debugging interfaces.

The Script Debugger provides the same functionality as traditional debuggers, including the ability to:

Set and clear breakpoints.
Step through and over procedures.
Display and change the values of variables and properties.
Evaluate expressions.
View the call stack, and navigate to any currently loaded procedure.

The Script Debugger also gives developers the ability to open and edit HTML pages. The Script Debugger supports script colorization for maximum readability.
