Example text

Delphi creates and changes this file as you create and delete new source for the project and so, although it is a text file, it should never be necessary to change it manually. Unit Source Files and Graphical Form Files You can create as many PAS files as you wish for your project; however, when you create a new application only a single PAS file is created. Each contains Pascal source code. A file may form a part of one or more projects. PAS files are often connected with DFM files, which contain a graphical description of a form.
