It was nice that "extra" steps like compilation and linking weren't required, but C can be used for interactive development too. Compiling and linking is quick for small files. On this machine, it's usually done before I can type another key after 'enter' on this four year old machine. The code size of many applications hasn't increased as fast as processing speed. Yes, it would've taken some time on a 1Mhz 6502, three decades ago. Anyway, once the program becomes large, you just need to break the code into multiple small files, compile a small part, relink all the parts. It's simple, quick, albeit not as convenient. I know I've mentioned this to both Hugh and Ms. Rather before... As for the need for "complex and expensive emulatore and debuggers", all you need for C is printf() to debug. No joke. I implemented about half of a rudimentary x86 PC operating system this way quite rapidly. Like Forth, C provides necessary low-level access to code an OS. Forget about the debugger, the only time, one time, that I ever had to use one was for a 1MLoc active of 5Mloc, multiple parallel process application. It was needed to follow data passed between separate processes since there was no other way to do that. >> > Forth is an unstructured programming language.

It's true that it doesn't have an explicitly named GOTO . However, most interpreter based Forth's have BRANCH . Just what do you think that does? Many of them have AHEAD and AGAIN too which are simple wrappers around BRANCH or it's equivalent if not present. And, the assembly language Forth's just use the host's jump instruction.
