Re: [colorforth] Attempt to reassemble colorforth: the Mark Slicker bug


It boots, there is something definitly wrong.

Hi Albert, 
Ray here: 

I does boot, and the command `boot' is active. the editor loads with
`e'. the blocks don't show up in the editor and the words on 18 and
beyond do not show up in the editor, and none of that code loads or
works.

I pulled the image thru the cf2html to be sure that the colorforth
blocks were there, and they are, they just don't show in the editor.

This is not entirely true, "18 edit" and your looking at the icons
EDIT block on 18.

I think the code is offset some how, tho I don't know how at this point.
