How to make this kind of text UI?

Use a text UI library. The Curses library used to be a popular option, but it is limited by copyrights.

Fortunately, there is an uncopyrighted version available.

This is called the "Console" mode.

Depending on your development environment and language of choice, it can be as simple as Ctrl+Shift+N, "Console Project" (in Visual Studio), or tweaking compiler flags (for C++). Every IDE/language provide a way to do this.

In Windows, the Console operates in two ways. Firstly, any project can create, attach to, and modify any number of console windows whenever it wants. Secondly, with a special flag in the EXE, the project will start up already attached to a console.

The latter operates subtly differently from the former. If you want a "normal" console application, I strongly suggest against creating and attaching to consoles. Just use the Console mode compiler setting.

Clipper was a popular way to do this in DOS.

I guess this is an old Clipper program. I so, there is still active support and even GUI libraries. I suggest you try xharbour. It's not DOS anymore but pure windows based. There is a free version and a pay version (visual xHarbour). With this tool you can even access SQL databases and it's 100% clipper compatible.
