In my Diploma 1992 I wrote a programm for calculate static frameworks.
I used Tom Zimmers F-PC for that - my favotit Forth for DOS(1992).
So I wrote much routins for calculate matrices etc.
Since 2021 (the covid years) I port it to Windows by useing win32forth and the old stuff.
Now I write more extentions for dynamic analysis with Eigenwert etc.
