Delphi Path Variables

Question

In the Delphi IDE, the path to the Delphi installation is specified as $(DELPHI). I am wondering if there is a way to create my own path indicators, such as $(MY_LIBRARY) or something similar. I thought $(DELPHI) was specified as an environment variable, but apparently not. Any ideas? (I'm using Delphi 7)

In Delphi 2010:

• select Tools -> Options
• select "Environment Variables"
• specify either System, either User variable
