        On this page you will find some rather simply examples of QuickBasic files wich probably may interest those,yet passionally fond of this application.Simply open the file to save or stamp it.The  “Answers” of the “Problems” are in orthogonal and in curvilinear coordinates.

If you want to open and stamp it clic on the .doc file.If you want to prove it clic on the .bas file,change the “Functions” and the “Variables” according to your wishes and run it.
