Greetings,
I used to write software in the days of Pascal, and since then have moved into other IT areas. I am returning to the programming world but since I was last there, an explosion of languages, frameworks, methodologies, etc, have taken place. Could anyone point me in the best direction to start my journery (language(s), IDE(s), etc)?

A lot depends on your goals. What are you aiming at?
Desktop v Mobile v Web for example can influence your choice.
What about your target OS? Also important.
Professional v personal developments may mean different choices.
It is impossible to answer your question without knowing this sort of information.

If you wanted to leverage your Pascal knowledge for personal projects you could consider Delphi or Free Pascal, but the job market is poor for these skills. If that matters, take a look at job sites covering your area and see what is in demand.
