47749087ac Make use of prototypes to silence warnings.
Change include() so it will be able to load files with forth code,
instead of just builtins. Remove #@- from the include section of the
help file, since they don't work in the new version of include, unless
BOOT_FORTH is not defined.

Change bf_run() so it will return the result returned by ficlExec(). Also,
make bf_run() push "interpret" to be executed by ficlExec(), since ficlExec()
doesn't do it by itself. (Things worked previously because nothing
recursed through ficlExec() by the way of bf_run()).

Change/extend comments on builtin behavior.

Search for "interpret" at the end of bf_init(), so /boot/boot.4th can
provide it's own version.

Remove dead code.

interp.c
	Rename the 'source' command to 'include' in order to avoid conflict
	with the ANS Forth command of the same name. (kern/9473)

interp_forth.c:
	Changes from kern/9412 (EXCEPTION word), kern/9442 (TIB buffer
	sizing) and an improved version of kern/9460 (set
	version numbers).

load_aout.c:
	Trim some obsolete #if 0'ed cruft.

pnp.c:
	Tidy the pnpscan output, turn off the module scanning until we
	sort out how to do it right.

4cd1140888 Fix variable initialization.. It was written with '==' instead of '-'.
#include <string.h> for string prototypes.

1c49fb07d8 * Begin integration of built-ins with Forth: leave the exit code from
a built-in command on Forth stack.
* Fix a bug which was causing a panic when loading stripped aout kernels.

ed82a24960 Eliminate much code cruft by extending simple file I/O API to include
fopen and fclose.  Also look for /boot/boot.4th now and, if found,
load its contents.

c412a7ae32 Don't have debugging on by default - it makes testing annoying. :) 1998-11-07 03:44:10 +00:00

8a34f8ba88 Ack. Create parseable command tail properly, and eat args out of the TIB. 1998-11-06 03:50:44 +00:00

84924924e1 Don't use the poxy vmGetString interface (who uses counted strings these
days?), get the input buffer ourselves.  Add some debugging code.

82f35547c9 Remember a bit more of my forth and do:
o Add fexists word to check for the presence of a file
o make fexists and fload immediate words which DTRT both interpreted
  and compiled (doh!)
o add an init word which gets run at bootstrapping time to do extra
  post-coldload initialization (in the default implementation, we
  look for /boot/boot.4th and load it if found).

c7db92c026 Add BootForth hooks; if BOOT_FORTH is defined, pass every line read
to the Forth interpreter.  Instantiate all of our inbuilt commands
as Forth words, and handle them being called from there.

Add my copyright to the bcache module (oops).
