General Development "Coming from a background in higher-level languages like Ruby, Scheme, or Haskell, learning C can be challenging. In addition to having to wrestle with C's lower-level features like manual memory management and pointers, you have to make do without a REPL. Once you get used to exploratory programming in a REPL, having to deal with the write-compile-run loop is a bit of a bummer. It occurred to me recently that I could use gdb as a pseudo-REPL for C. I've been experimenting with using gdb as a tool for learning C, rather than merely debugging C, and it's a lot of fun. My goal in this post is to show you that gdb is a great tool for learning C. I'll introduce you to a few of my favorite gdb commands, and then I'll demonstrate how you can use gdb to understand a notoriously tricky part of C: the difference between arrays and pointers."

That's why it's worthy to learn Forth - especially, if you still got your C-64; it's too "weak" to use C (yes, there is "Power C" for C-64, but it's somewhat limited) - but it's strong enough for Forth! My recommendation would be Blazin' Forth or Super-Forth 64. For Linux/Windows G-Forth could be probably the best learning environment (or commercial SwiftForth, which is free for personal use).
