another smallification

[Jack Andrews]

is there a shorter k expression for:

  k)`a`b {.[x;();{x::y};y]}' 2?10

?  

i'm fussy:     p:2?10;a:*p;b:p 1  doesn't count.  

i'm looking for  a shorter

  k){.[x;();{x::y};y]}

thanks guys  :j

I don't think you need that at all

q)`a`b set'2?10
k)`a`b .[;();:;]'2?10

Cheers,
Attila

q)`a`b set'2?10
k)`a`b .[;();:;]'2?10

i want to use :: coz my expr is in a while loop and I want to set a and b globally

 

[Felix Lungu]

then qualify `a and `b.

[Jack Andrews]

no hits on code.kx.com for "qualify"

[Attila Vrabecz]

set is always global

You cannot refer to a parameter or local by name at all

(as they are on the stack)

Only complication is that set always works in the current namespace

What Felix probably means is that you can do `..a to make sure it is main namespace - however that is only needed if you are working with namespaces

namespaces. qualify the names in their namespace.

the main one is `.. , so `..a`..b set'2?10 does the trick but set does it globally anyway even inside of a lambda.

`a`b set… is enough.

nice one.  and i see a clever projection here.  and i now see that : operates 

globally in the . (apply) from other messages in the thread

thanks,

jack.
