This set of patches: - adds a `Base` variable - adds `decimal`, `hex`, `octal`, and `binary` - extends `s:to-number` to support `Base` - extends `n:to-string` to support `Base` - updates the glossary to cover these Additionally: - removes the 1024 cell limit for the kernel - adds a header cell (7) for the start of the text input buffer - adds a header cell (8) for the end of the text input buffer - updates most Nga implementations that use the text input buffer to look at this instead of hard coding the address FossilOrigin-Name: 391ad6fc0187e5ff3089d5c42d5d5e1c18fd0b2379c90a148ba44bb66145f020 |

Retro is a modern, pragmatic Forth drawing influences from many
sources. It's clean, elegant, tiny, and easy to grasp and adapt
to various uses.
Features:
- Open Source (ISC License)
- Portable (runs on a MISC-style virtual machine)
- Small source & binaries
- Builds into a single, self contained binary for easy deployment
- Sources in literate format, using a Markdown variant
## Quick Start
For most systems (FreeBSD, NetBSD, OpenBSD, macOS, Linux):
make
You will need a standard C compiler and `make`.
## Executables
Binaries will be placed in the `bin` directory.
The primary executable is `retro`. This is used for running the
examples and the Atua (gopher) & Casket (http) servers that
power forthworks.com.
The `retro` executable embeds the image into the binary, making
it trivial to copy and deploy.
This interface layer also extends the language with many new
words and vocabularies, adds scripting, file i/o, floating point,
and more.
The `retro` executable can handle a variety of command line
arguments which are covered in the manpage, but the most common
ones are:
retro
Starts the *listener*, a basic REPL for interactive use.
retro filename
This will run the code in the specified file, then exit. This
is also used to run programs as shell-type scripts using a
header line like `#!/usr/bin/env retro`.
retro -i -f filename
This will run the code in the specified file, then start the
listener.
## Literate Sources
Source files for use with `retro` are written with code in
fenced blocks:

Anything outside the fenced blocks will be ignored.
## Documentation
The primary documentation is in RETRO-Book.md (and the formatted
epub.) Additional notes can be found in the `doc` directory.
## Alternative Implementations
In addition to the C and Python implementations, this source
tree includes additional implementations in C#, Nim, JavaScript,
and Pascal. These are not as well tested or as feature complete
as the main implementations, but are provided for your use if
the standard implementations will not suffice.
## Patreon

Pateron are put into development related expenses (server expenses,
app store fees, hardware).
