When I first learned to code with Delphi, I used Delphi 6 Professional.
I loved that program, and one of its features was right-clicking on the form and choosing to view the DPR Source.
You may be asking, "WHY?"
Sometimes, you will need to add or edit this code.

How do you view the DPR code in the newer versions of Delphi?
(I am using Delphi 11 Community Edition)

From the Menu.
