Tcl script error

[Altera_Forum]

Hi: 

I am new to Tcl script. I download a simple program from the website, and copy it onto the Tcl script, and try to compile it.   It's just a one line code    puts "hello world"   However, I constantly getting a compilation error of Top-level design entity is undefined   don't know why     Thanks
