You're probably referring to the Delphi development environment. The Personal version, because only this one is free, can be downloaded from the website
www.borland.com . You only need to register to receive a registration key for the product. Unfortunately, programs in this version cannot be distributed as commercial. But if you are not going to make money from your programs then this version is just right for you. However, if you are going to create commercial prototypes, I do not recommend buying the latest version of Delphi. The latest version is called Delphi 2005, I don't remember the price, but it is definitely over 4 thousand. dollars. I recommend the slightly older version of Delphi 5 for a little over $1,300. The choice is yours.
