It's now a simple flag updated by the C< implementation. No more routine pointer. The goal is to avoid tons of "ok" during a LOAD operation.

C<? is a flag indicating whether a character is waiting in the
|
|
input stream. 1 means yes, 0 means no. It is the responsibility
|
|
of C<* to update that flag.

WORDBUF is the buffer used by WORD
|

|
|
BOOT C< PTR is used when Forth boots from in-memory
|
|
source. See "Initialization sequence" below.

|
INTJUMP All RST offsets (well, not *all* at this moment, I
|
|
still have to free those slots...) in boot binaries are made to
|
|
jump to this address. If you use one of those slots for an
|
|
interrupt, write a jump to the appropriate offset in that RAM
|
|
location.
