I checked the Iverson’s Dictionary of J (Vector Vol7 No.2, October 1990); the 
parsing table, as far as I can see, only allowed verbal hooks (and forks).  
Thus, adverbial and conjunctional hooks (and forks) were introduced between 
late1990 and 1992.  I must say than when most of the adverbial and 
conjunctional hooks (and forks) were decommissioned I was not particularly 
concerned because I was (and I still am) using 'apply' (128:!2) for tacit 
meta-programming; however, knowing what I know now, I wish at least I had 
argued to keep the (c a) hook.

By the way, the same issue of Vector reports:
"
APL/? has been named 'J'. Apparently even Ken Iverson does not know the reason 
why that particular name was chosen, although he must have assented to the 
name. Roger Hui chose it and keeps his reasons secret.
"

DB> PS: BTW, the quotes in your message are coming out weird and messing up the 
format of 
DB> your text. Are you using a "smart quote" feature? Outlook, Word, and some 
web interfaces 
DB> (using RTF browser toolbars) turn these on by default. I've never found 
them helpful (but 

I am a afraid that I was using inadvertently that feature (fortunately it does 
not look too bad in the archive: 
http://www.jsoftware.com/pipermail/programming/2009-December/017145.html).    I 
use often use Microsoft Works Word Processor with my EeePC; any hints on how to 
turn this feature off?

Whoops, forgot the URL:  http://www.jsoftware.com/help/dictionary/dictf.htm  

JQ>  I did not mean very detailed in a pejorative sense

DB>  at no time was I offended.

I just realized that this message caused the very problem it attempted to 
allay, because I wasn't clear that I was writing for a broader audience and not 
specifically you!  

How strangely recursive.
