Logo was one of the 3 I first picked up on Assembler, BASIC and Logo. My first computers weren't capable of running LOGO (no real display). I didn't have a LOGO interpreter so I coded one in BASIC. By god it was slow. But I did pick up structured programming and it led me on to LISP (and SASL/CLU,Pascal,Modula 2). Somehow I still ended up using C/C++ daily. I guess that's just how it goes. But LOGO was and is nice. It (almost) has what my dad calls IKR (Immediate Knowledge of Results) and if LOGO were to develop further it is exactly the area of realtime interactivity I think it should move. Great language with a lot of thought put into it but still very much a product of its era.
