Virgil Dupras 5c03b33982 forth: remove sysvarWord type 
Not needed anymore. CONSTANT does the trick.

Virgil Dupras 80985460d4 forth: remove JTBL 
We refer to stable offset as direct numbers instead of offset to JTBL.
Simpler that way.

I'll remember...

Virgil Dupras d2dcd96ce1 emul: add useful emul_trace() debugging tool 2020-03-29 22:13:54 -04:00
Virgil Dupras 48078d9c9c forth: Replace "SKIP?" with "(?br)" 
There is an alternate git history where I continued the Forth-ification of
words, including "SKIP?", but that was a bad idea: because that word was
written by flow control immediates, I stepped into quicksands where stability
became necessary in z80c.fs and I couldn't gracefully get out of it.

I'm stepping back and take this opportunity to replace the shoddy SKIP? algo
with a more straightforward (?br) implementation.

(br) and (?br) will always stay in boot code where it's easier manage a stable
ABI.

Virgil Dupras 41cd8086d4 forth: don't use "(entry)" in dummy.fs 
Because icore.fs defines it in a "not-for-runtime" manner, dummy.fs
executing it had ill effects. We use a workaround instead.
