Welcome to fig-forth-6809 Wiki

I think the current branch is auto-hand-optimized.

I currently think the path I took to get here was sort of as follows:

1: hand-translated

2: search-and-replace

3: auto

4: auto-hand-optimized-offline -- see NEXT loop for clues

5: auto-hand-optimized-detour (lopped branch)

6: auto-hand-optimized (current, JMP and JSR proceeding in parallel, in suspended animation)

The files from the first three steps don't seem to be in my junkpiles. The files here are actually what existed about steps 3 to 5.

master has not yet been merged with the current branch, in no small part because I kept getting interrupted in the processes and am not complete confident what happened when.

The source files of most interest are fig-forth-6809_jmp.asm and fig-forth-6809_ret.asm.

fig-forth-auto6809.asm was renamed fig-forth-6809_jmp.asm, because definitions return to the inner interpreter via JMP NEXT (or BRA/LBRA NEXT).

fig-forth-auto6809opt.asm was renamed fig-forth-6809_ret.asm, because defnitions return to the inner interpreter via the RET instruction, allowing some leaf definitions to operate as simple subroutines.

Either is a (presently buggy) implementation of a fig Forth kernel, which should assemble to function on the TRS-80/Tandy Color Computer.
