Virgil Dupras afc2327770 Split icore in 2 parts 
The goal is to insert device drivers in between.
 2020-05-08 21:47:03 -04:00
Virgil Dupras baf725aa38 Move a bunch of words from core to inner core 
That makes it easier to write drivers that can be xcompiled.

Virgil Dupras ffdc58739a ti84: HelloWorld! 
In emulator of course...
 2020-05-08 11:36:50 -04:00
Virgil Dupras b90efb0f7f ti84: first glyph on screen! 
On the emulator of course...
 2020-05-08 09:07:44 -04:00
Virgil Dupras 58ec54fc97 ti84: wip 
Gave more priority to CPU in the emulator because initialization would
otherwise be horrendously slow.

Virgil Dupras 114e753b64 ti84: WIP 2020-05-08 06:50:34 -04:00

Virgil Dupras 204a9c69f8 editor: fix PSP leak in F 2020-05-07 08:38:57 -04:00
Virgil Dupras feb0411530 editor: simplify I with the use of MOVE- 
Also, delay the shadowing of DO..LOOP's I for as long as possible.
 2020-05-06 21:10:27 -04:00
Virgil Dupras eaeb138a0c Add words C@- C!- and MOVE- 2020-05-06 20:37:08 -04:00
Virgil Dupras 690d9e6313 editor: improve I

 2020-05-06 17:41:49 -04:00
Virgil Dupras 58ece9f9a1 editor: implement I command 
Also, made LIST properly handle full 64-chars lines not ending with
a null or CR. Previously, such a line would be accompanied by its
following line, duplicating that line's output.
 2020-05-06 12:19:36 -04:00
Virgil Dupras f54b1dc504 Add 2>R and 2R> 
This allows us to make DO..LOOP more compact.

Virgil Dupras 60b4bbf28a Fix DUMP's broken "round up to next 8" logic 
This was caused by the removal of signed-ness a long while ago.

Virgil Dupras 9df053b76c z80a: add CPn, 2020-05-05 21:49:26 -04:00
Virgil Dupras fa79e3d8a6 Make (print) stop on CR 
Lines edited with the Block editor end with 0xd and (print) spits
spurious CR when printing those lines.

Also, properly initialize ACC in BROWSE.
 2020-05-05 15:49:50 -04:00

Virgil Dupras 8ef197d248 Make linker more compact 
There was a weird empty block in the middle of the program.
 2020-05-03 20:33:36 -04:00
Virgil Dupras a96b5f1dec Restore DOES> section in usage guide 
I removed it because it was redundant with Starting Forth, but
I directly reference it in the dictionary, so well...

With all this recent movements, we had a bit of a fragmentation
issue.
 2020-05-02 21:47:32 -04:00

Virgil Dupras 2a578b3352 editor: implement F 2020-05-01 21:52:38 -04:00
Virgil Dupras ecca70c7f3 Add layer of indirection to EMIT 
This would allow things like temporary giving control to the *CL
line on the TRS-80. For example... A very far fetched example. Not
at all the only *raison d'etre* of the layer...
