Some code written in college, for some civil engineering classes.
Maybe it helps someone, maybe not.
Sorry, but the code wasn't originaly commented/translated and I lack the time to do so.
###How to use### You'll need HPUserEdit IDE to view/edit/test code ( or any other editor combined with a real calculator or an emulator ).
This used to be available at HpCalc.
Another application that worth mentioning is TGV Editor, also available for free at HpCalc.
