I want to learn to write custom code in Inno-Setup installers using the [code] section.
I want to know which programming language is used for that purpose and if there’s a book or books I can read to know the language syntax, learn typical usage and see practical examples.
Inno Setup’s
[Code]section uses Pascal (or Pascal Script to be more exact, thanks to TLama), likely because Inno Setup itself is written in Pascal Delphi.For books on pascal, see https://stackoverflow.com/q/1665458/492336
