PascalScripts are script programs that are written in Pascal. They will be supported by the macro system of upcoming versions of Lazarus. Additionally, PascalScripts may be executed directly by the shell with help of the InstantFPC tool.
PascalScripts are also supported by several third party applications, e.g. Inno Setup.
PascalScript is not to be confused with Pascal Script, an ObjectPascal/Delphi/Lazarus compatible interpreter with bytecode compiler by RemObjects.
