Pascal scripting

Prior to the release of Inno Setup version 4.0, an enhanced version of the product called My Inno Setup Extensions was available from another author who took the Inno Setup source and added to it. One of the primary features offered by My Inno Setup Extensions was the ability to write Pascal script, which can be used to provide additional customization beyond what Inno Setup itself can do. With the release of Inno Setup version 4.0, the enhancements previously found in My Inno Setup Extensions are incorporated into Inno Setup itself.

You can add Pascal script to an Inno Setup ISS file by including a Code section. Within the Code section, you can write code to do all sorts of things not possible within Inno Setup itself, such as adding additional wizard pages and creating your own functions. The Inno Setup Help file describes some of the things you can accomplish with Pascal scripting, and also has some code examples to get you started.

Keep in mind that you do not have to use Pascal scripting to create a fully functional setup package with Inno Setup, though. It ‚ s just one more nice feature now available.
