Why does Forth return -1 as a flag for True?
forth
Solution
-1 is all bits set which then has the benefit that words such as `and`, `or`, `not`, ... serve as both logical and bitwise operators (as opposed to say C with `&&`, `||`, `!`, ... vs. `&`, `|`, `~`, ...)
Problem
The Forth code ``` 7 3 > . (7 > 3) ``` returns `-1`, but every other language I've ever used uses `1` as a flag for true. Why is this? What accounts for this difference?
