Hi Andrey,
My first idea is infix, the dyadic mode of \ feeding into monadic transpose |:
t=. |: @: (_2 ]\ ])
t 0 1 2 3 4 5 6 7
0 2 4 6
1 3 5 7
Others will have more informed feelings about the best way, but this would work.
Cheers, bob

They both look fine to me on Apple Mail (once I had changed the font for
message content to fixed width)

Hi Devon!
Both look fine for me. Using our corporate Outlook client (Office
Professional Plus 2010).
On the Apple Mail app the spacing is messed up and there seems to be an extra
carriage return between each line.

Hi Jon,
The path to the script that defines launch, fork and spawn is
jpath '~system/main/task.ijs'
If you give that script a read you might find what you need.
Hope this helps.

Hi Linda,
I don't know of a way to do it on the standard menus since jhs does not have a
config option, but since it is controlled by CSS in HTML you could use
jhtml_jhs_ 'style type=text/css*{font-family:courier
new,courier,monospace;}/style'
with the appropriate values for the font-family

Hi Linda,
Maybe try
k=: 13 :'@{:@,@y'
instead of
k=: 13 ::'@{:@,@y'
When each character carries so much information, typos become a big issue. Hope
this helps.

Linda,
What are these games you speak of? (just kidding, Go 'Hawks - oh yeah that's
next week)
After a long and circuitous route that I won't go into, and with the benefit of
Raul and Pascal's responses, I came up with this:
postable=:1 : (':'; '(((#~LF-.@e.])5!:5''u'');,.y),.({.;}.)(#~

Hi Linda,
The way I remember this effect is to imagine that when you define a verb
tacitly the last step is to parenthesize it in your mind.
So,
enc =: ;@:(/.~ 0 1 2 1 $~ #)
becomes
enc =: (;@:(/.~ 0 1 2 1 $~ #))
and stays the same, while
;(/.~ (0 1 2 1 $~ #))A
works as expected
Raul,
Labs can be created just using a text editor, but if you really want to use
Author, I have created labs in 602 with Author and just moved the lab file
created over to the lab folder in j802.

Hi Brian
Ctrl-D and Cmd-D have no effect, but Ctrl-Shift-Up is pretty much muscle memory
for me and works as advertised in JHS. Cmd-Shift-Up selects the screen above
the cursor.

A quick idea on my way out the door.
create a vector of N 1's
N#1
add a random vector of N 0's and a single 1
(i.=?)N
Sum the new vector V' and exit if +/V' is equal to Q (probably a converging
power conjunction)

Not really a silly idea and in fact as you have described it, it sounds like
the idea behind tie and agenda
v1`v2`v3 @. v where v1, v2,v3 are the different verbs and v is the verb that
returns the index into the list of gerunds.
