# Line Compiler Directive in F# The `#line` compiler directive is used to properly identify line numbers when dealing with generated code, as the line numbers in the generated file won't match. You can use it to provide the original path of the file as well. ```fsharp #line 25 #line 25 "C:\\Projects\\MyProject\\MyProject\\Script1" #line 25 @"C:\Projects\MyProject\MyProject\Script1" ```
