What I did Wrong in my Verilog Project? (Quartus cannot compile it)

Dear FvM,

thank you very much for your kind suggestion. Due to your help and helps in other forums I was able to rewrite this example such a way that it compile and looks reasonable in RTL.

In regards to "My_Frist_Project" it is really my first project, I never used Verilog/VHDL or other synthes languages before, however, it is really simple algorithm regarding to my goal - QR like algorithm. Hope that my experience in numerical mathematics helps me to implement it fast enough :)

Sincerely,

Ilghiz
