06:49:01 <crcx> hi docl; I added your prepend and append to the strings' vocabulary
06:51:36 <docl> cool

17:30:31 <crc> hi roarde 
17:30:37 <roarde> grrrr
17:32:28 <crc> problem?
17:35:52 <roarde> in what sense does 10.7 break 10.6?  Does it break, for example, 10.4?
17:36:16 <crc> 10.7 has a new vocabulary implementation, which is not compatible with the vocabularies used in 10.6
17:36:39 <roarde> oh. That I was expecting.
17:37:01 <roarde> hello, then :)
17:37:01 <crc> that's the only significant change in terms of compatibility
17:37:48 <crc> (beyond 10.7, there'll be big changes though....)
17:37:52 <crc> how's it going?
17:38:48 <roarde> so-called "rl" is fine, at a real crossroads with computers, etc.
17:40:33 <roarde> a bit of reading about arrayforth suggests that some of the aha ideas have been incorporated. know whether that's so?

17:44:59 <crc> I'm not familiar with aha
17:45:46 <roarde> k, thanks. If you're curious, it's on the timeline at ultratechnology. Don't think it was ever quite complete.

19:24:05 <foucist> crc: what exactly is not compatible
19:24:19 <foucist> crc: basically you dropped some 10.6 vocabular45y
19:24:22 <crc> foucist: the implementation is completely different
19:24:34 <foucist> how many 10.6 words did you drop
19:24:36 <foucist> approx
19:25:02 <foucist> how is the implementation completely differnt?
19:25:04 <foucist> it's a forth isn't it?
19:25:24 <crc> 10.6 had nestable, collapsable subchains for vocabularies. it was a clever technique docl came up with. 10.7 has completely separate linked lists, with a user selectable search order
19:26:01 <foucist> what search order?
19:26:37 <crc> in 10.7, you can load the vocabularies in a particular order. vocabularies get searched before the global dictionary in the new approach
19:29:36 <foucist> it makes sense that newer vocab would get searched before global dictionary anyways
19:29:41 <foucist> isn't that how it was before
19:30:22 <crc> in the old system everything existed in the global dictionary; it was just possible to collapse some portions of it
