Word is an internal call, it's a function, but the key is that the parameters and local variables are on the data stack and are separate from the return stack. I can call many levels without touching the data stack! Impossible in other languages. However, this does require practice and a change of mindset. At runtime, the dictionary doesn't exist, and under certain conditions and with the correct compiler, the stack doesn't either; it's converted into registers.

ANN: Second generation language derived from colorforth

phreda4 — Sat, 12 Oct 2019 21:24:29 +0000

After more than 10 years of developing r4, a concatenative language derived from colorforth, I begin the development of r3, the second generation of this branch of languages.

The R3 language is based on 64-bit processors, simplifying the construction of code blocks, the word ")(" is deprecated.

With respect to the VM, is 64 bit, it is configurable in the code of each program, the size of the free memory, the graphic window and others. The inner interpreter of VM are dword base, not more bytecodes.

It is currently in development, transferring and improving the development environment.
