It copied one too much.

It simply didn't work before, except for =.

Simpler code, more predictable output.

Interpreter is functional in the emulator!

Red 5 standing by.

Since the fix of its RAM addr, we use the wrong CURRENT in every
usage of IMMEDIATE in icore. We therefore have to manually set the
flag for all 3 immediate words in that unit.

This should help with the bootstrapping of non-emulated environment.
For example, I have a problem with the RC2014: I can't send it
bootstrap info until the ACIA is up. I need to find a way...

To update LATEST offset more easily. Will be useful for recipes.

It was badly handled.

All "stop pings" are now explicitly made at appropriate places. This
fixes a problem I've introduced in the last commit where RAM+ was
unexpectedly part of a stable ABI because of "HERE" usage in dummy.fs.

This system will, anyways, soon change because boot.bin and z80c.bin
will be built during the same process (but there's a bit of retooling
to do before I get there).

Doing this was a bit stupid. These offsets are constants. Moreover,
having them in stable ABI had us construct the boot binary from the
stable ABI of the host, making it very difficult to change RAMSTART
for a new system.

This commit cuts Forth's dependency on zasm. It now self-assembles
its own boot-binary! Things are a bit messy now, I'll clean up
later.

Make LATEST configurable through a value in the binary instead of through
a ZASM constant. This enables the simple concatenation of compiled dicts and
simplifies the build process.

Not needed anymore. CONSTANT does the trick.

Now we're having a real nice and tidy forth.asm...
