I think this radio model could map the problem space for a centralized system that maintained a list of items and their prices which needed to be broadcast to the retail outlets on a regular basis.
Or a common cache storage to make some complex data manipulation calculations centrally performed available to a large number of satellites who just need the end results but do not have the need to do local calculation.
Is this tool suitable for any other story system ? It might be a lot of work to extract the Vampire the Masquerade dependency and allow this to be a more generic tool to support stories in a different world but it does seem mansueli has done a lot of useful work here.

Does writing Llama.cpp mean that it is using any object oriented Lisp code ?
M allows one to code in a very terse language (an artifact of only 2K RAM/ transient temporary memory) with so many abbreviations and short forms for intrinsic/builtin functions, variables, commands, and other things. A large number of string manipulation, mathematical, and logical functions with a form of string recognition matching (from SNOBOL) and type coercion/interpretation round out the basic expression evaluation system. Allowing variable names as valid values for any variable gives a way to create dynamic expressions and symbolic manipulation.
A fixed point numeric value with over 18 digits of accuracy means math on values over the national debt can be stored in a single variable. Lossy floating point systems of other computer languages are not acceptable to customers. Limits on strings of characters depend on implementations and have been only increasing over the years beyond megabytes. All of these are managed without applications dealing with pointer arithmetic, allocation, deallocation, and such schemes such as Rust, C++, require.
The decision to separate out I/O into a subsystem was very common at the time, with various kinds of devices providing a high level model of channels & streams that are all managed below the language implementation level. Tight limits and timing for input I/O and output I/O means no buffer overflow exploits. Character set management also keeps control over contents of strings.
Generally, M has follows the model of high level capabilities under a very simple language interface. Each command has a highly focused syntax.
Which is why permanent storage uses a dynamic sparse variable indexed by strings whose stored values are strings and is indicated using the caret ^ as the prefix to the variable name. This approach removed the need for user level applications to track disk latency, disk buffers, asynchronous processes, etc. which were common at that time.
Interprocess communication and control using a hierarchical Locking mechanism is very flexible. This means coordinating by locking a high level entry in the hierarchy and allow other worker processes to lock lower in the hierarchy.
The 1977 standard used a system that prevents deadlock from occurring. Later M Standards broadened the tools available with incremental & decremental locking and now deadlock can happen.
Transaction Processing allows one to separate data updates in a transparent way so competing control flows can more intelligently change the system. Basically, this allows a try-retry-commit-stop backtracking command flow similar to Prolog and declarative code.
Control flow also uses the parallel invocation command (JOB) and normal subroutine calls (DO), with parameter passing and function return values. Looping is unified by the FOR command. Exception processing and control flow avoid undefined behavior.
Dynamic variable lifetimes using KILL and the NEW commands and associative memory access to values of variables. Typed controlled run time evaluation of commands adds discipline beyond "eval" in other languages.
The language allows implementations to specify unique abilities to increase unique commercial subsystems while still being backward compatible. There are ways to invoke external code which can enhance capabilities as well as tieing to SQL and other languages.
While not part of the standard, high performance and reliable database management with ability to automatically recover from power loss using internal logging and rebuild tools, and compressed B*-trees is necessary for any M system to be viable in the market.
There is also the term CHUI for Character User Interface that is contrasted with TUI.
Also, does it support visible control characters ? EXACT EMULATION ? 3270 ? VT-105 ? VT-220 ? VT-320 ? VT-420 ? SIXEL ? NAPLPS ?
This seems to say flags is a sort of unsigned integer.
Is there a way to break the flags into big endiaN bits where the first two bits are either 01 or 10 but not 00 or 11 with 01 meaning DATA and 01 meaning POINTER with the next five bits as a counter of segments and the next bit is 1 if the default is BLACK and 1 if the default is WHITE ?
It is an interesting thought experiment re instruction pipelining in a virtual machine or interpreter design. What would you change in a design to allow it ? Would an asynchronous architecture be necessary ? How would you merge control flow together efficiently to take advantage of it ?
This is a good write up that doesn’t require DuckDB as it isn’t specific to a particular database.
I didn’t know there was an open source version of the Watcom compilers and a 16-bit library to support them.
