# JonesForth ARM64 with APL symbols
This is an ARMv8 AArch64 version of Richard W.M. Jones' original x86 JonesForth.
I have added a few things including:
- Defining words
- Combinators
- Delimited continuations
Also I have used the APL character set.
The pizza is in the examples dir but by way of garlic bread:
```
∇ ε ( ⌈⌊ ⊤ - ↑ ∥) ↓ ∇ / Define ε as Euclid's algorithm /
∇ λ ◁ , ▷ @ ⍎ ∇ / A defining word λ which names anonymous functions /
3 ⊂ ↑ ⊃ ⊂ + ⊃ cat ⍎ / Double three using the cat combinator /
1 2 3 4 ⊂ × ⟦ + - ⊃ ⟧ ⍎ / Capture '+ -' in a delimited continuation with ⟦ ⟧ /
```
ASCII equivalents for APL-character words are defined in ascii.f (they are the
corresponding Forth words where applicable so ascii.f makes a handy glossary).
You can compile and run with
gcc -nostdlib jonesforth.S
cat jonesforth.f - | ./a.out
and run the the examples like
cat jonesforth.f examples/sockets.f - | ./a.out
You may need to
stty iutf8
if your terminal isn't set up to handle utf8 by default.
