You now know

These are all the programming tools that were available till the general acceptance of object oriented programming (needed for very large programs) in the 1990s.

You can do a lot of programming with what you have now. Sure there's the arcane syntax associated with each language, which you'll pick up in time, but you have the logical basics. At this point you could in principle go off and teach yourself all the non-object oriented languages. What you need now is practice at putting problems into a format, which can use these tools. (This includes learning standard algorithms.)
