eval is not working

[promistrio]

Hello! I launched HardwareSimulator.bat and opened different *.hdl files from projects/01. After changing imput pins "Eval" button don't working. All scripts return error on the eval line

The "Eval" button will not be enabled unless all the pins named in the OUT section are connected to parts in the PARTS: section.

Until you write the code, the HDL files in projects/01 have nothing in their PARTS: sections, so they will not work in the HardwareSimulator.

You can experiment with the HardwareSimulator using the projects/demo/Xor.hdl file which is a working example.

If I load the demo/Xor.hdl, the eval button still isn't active.

That demo in the book was intended to let you see how to connect several parts together to implement a schematic. It is not a "do this first" circuit. It will not work unless you have either implemented the gates it depends on, or removed the .hdl files for those chips from your directory so that the simulator will use built in parts.
