What is this fascination with exclamation marks, sweetchunks?

Crikey, no two C compilers are the same and they have different
undefined behaviours! Stop using C immediately. There's a whole
world out there that does not use gcc or FOSS tools.

There are a few (three or four) professional grade implementations,
and a huge number of amateur implementations that end up as
abandonware after a few years.

The vast majority of the amateur implementations are threaded code
systems as descibed in Loeliger's book. However, for the last 20 years
or so, the professional implementation generate optimised native code.
These implementations follow the ANS 1994 and Forth-2012 standards.

Compared to other minority languages, Forth has survived very well.
Our cross compilers for embedded systems include USB and TCP/IP
stacks. We have been doing what is now called IoT for 20 years.

Very few users of professional Forth systems lurk or post on
comp.lang.forth.

P.S. Please note that I prefer to be collaborative as more information
is exchanged than in a combative debating style. It's not a matter
of winning or losing, but of providing correct information. After
that it's down to philosophy and taste, which are worth discussing.

P.P.S. If you want to know how CREATE ... DOES> works in a modern
system such as VFX, download one of the Linux or Windows evaluation
versions, and decompile the results. If you have forgotten how to
use Forth, see our Forth books page.
