With how much source/object code? – Chuck Moore, the inventor of Forth Source: http://yosefk.com/blog/my-history-with-forth-stack-machines.html http://yosefk.com/blog/my-history-with-forth-stack-machines.... 500 lines are actually possible since Forth words are threaded. That means, any new defined word w can take advantage of all available predefined words. Follwing words can take advantage of w, etc. Forth words are not just simple procedures but they can also comprise new syntax structures. Forth words can be "procedures" or "macros", and both can be mixed freely. Threaded code was the main reason why Forth was so successful in the first years when memory costs were a real issue.
