Programming For a 7 Year Old

I am not a software programmer, but I would like my young children to start learning the basics of progamming and logic. In the early days of Commodore 64, the BASIC language was so simple. The first time a child typed
10 Print “Dog”
20 Goto 10
was a thrill.
Nowadays it seems the languages (or the development environments for those languages) are so complicated. Is there a programming language/environment specifically designed to teach children?
