2021-12-15 05:26:44 <neuro_sys_  > I probably asked about this before but. 1) Why is the word being linked not visible until after the definition is done. 2) Is it mentioned in any of the standards? 3) and how do you implement it?

2021-12-15 05:38:06 <dave0       > so it can refer to a previous word of the same name
2021-12-15 05:38:19 <neuro_sys_  > Right
2021-12-15 05:38:26 <dave0       > the standard mentions it but i gotta look it up
2021-12-15 05:38:37 <neuro_sys_  > No worries. And how do you prefer to implement it?
2021-12-15 05:38:56 <neuro_sys_  > I first did it with a HIDDEN mask that I set, and unset with ;
2021-12-15 05:39:00 <neuro_sys_  > Not sure it's the best way though
2021-12-15 05:41:06 <dave0       > jonesforth does that.. sets a hidden flag
2021-12-15 05:41:52 <dave0       > i build a header in `:` but don't link it to the words list until `;`
2021-12-15 05:42:20 <dave0       > when i build the header, i stash the pointer to the header in the `LAST` variable
2021-12-15 05:43:04 <dave0       > then in `;` i use the `LAST` variable to poke the link field into the list
2021-12-15 05:45:15 <neuro_sys_  > I see. I use LAST variable to keep track of the tail of the dictionary linked list. It is used by FIND to find the words. So setting LAST right away would make it effectively visible.
2021-12-15 05:45:22 <dave0       > basically `;` does all the work of adding the word to the dictionary
2021-12-15 05:46:23 <dave0       > ah just use a different named variable
2021-12-15 05:47:17 <dave0       > the standard doesn't say you need to keep a pointer to the word you're defining, but in reality you probably do
2021-12-15 05:48:41 <dave0       > i also questioned using a HIDDEN flag :-)
2021-12-15 08:33:32 <veltas      > I also have a var for that

2021-12-15 08:40:50 <dave0       > i moved the add-to-list from : to ;
2021-12-15 08:41:12 <dave0       > hmm i'm gonna check what jonesforth did
2021-12-15 08:45:22 <dave0       > ah okay jonesforth used `LATEST` for both FIND and CREATE
2021-12-15 08:45:31 <dave0       > my method needs another variable

2021-12-15 17:04:49 <f-a         > is that recursive
2021-12-15 17:10:26 <neuro_sys_  > Not really, I just re-used the same name for the word in a way to extend its meaning.
