It worked well enough for K&R to develop their B language with it, which
begat C. 8-)

I though MR must be at least 99 by now...

I remember BCPL (Bloody Complicated Programming Language) had a copy
for my BBC computer back in my student days at
http://www.robinson.cam.ac.uk .
IIRC it was a simplified version of CPL (Complicated Programming Language)

Hi,
You might want to take a look at Martin Richards webpages - he invented BCPL

That's one direction to go with a VM, the other is to assume for
development, a small FLASH based system containing the VM itself, and
download to external SRAM. This has the advantage of possibly quicker d/l
cycle as burning flash is always slower and actual interactivity. For final
image burn, you can then provide the VM as a linkable library.

I've also worked with various intermediate code systems over the
years. Here's some thoughts I put together on a 16 bit embedded VM:

This is something that could offer portablity between various 16 bit
CPUs. I have 2 in mind: the Freescale hc12 family, and the MSP430 family.
I did not use objects in this concept because of the limited RAM.
If I do something like this for the ARM it will support objects and
will likely be similar to the Java VM. But I would add the ability to
dereference pointers in order to be more efficient with C programs.
Right now I'm building my hc12 debugger and this will keep me busy for
a while.

Aww, that's high tech, my first computer was the Tandy Microcomputer
training
kit, a 7-segment LED, and 8 LED's for binary output, along with a switch
grid
for hex input.
oh, and a speaker! Woo! Dang, I wonder if I still have that somewhere..

Back to the roots! :-) Remembering the old days. Just 2k ROM, 2k RAM and
a self made keyboard in front of the old eye killing b/w TV.
(I guess the ARM has plenty of ressources :-)

Talking about that, I have been trying to sift through the urban legends
and get the real story on how "Thumb code" got its name.
