Following is the implementation of rotate function Orig: k){$[0h>@y;'`rank;98h<@y;'`type;#y;,/|(0;mod[x;#y])_y;y]} Working by making slight changes in q {$[0h>(@)y;'`rank;$[ 98h<(@)y;'`type; [ (#)y;(,/)(|)(0;mod[x;(#)y])_y;y ] ] ] } How is the strike...

I think the the answer is strings are not interned, only symbols are. But just double checking.

tab:([] c1: til 10 ; c2:10 + til 10) /Both do not work ?[tab;til 10;(>;`c2;16)] ?[tab;til 10;(last `c2)]

Composition has many "weired" syntax . Are they overloads of adverbs ? Is '[f ff] overload of ' adverb Another example is '[;]/[(g;f;ff)]

How do I put a timeout on the following sync call ?h:hopen `:192.168.12.15:5001@[h;`func;{0N!x}]The other approach is doing an async call and putting a timeout on the callback. This is something I am not looking for.Thanks.

Thanks @SJT and @gyorokpeter-kx l / 2 3 5 7 11j 2 rotate l / 5 7 11 2 3j {$[0h>(@)y;'`rank; 98h<(@)y;'`type; (#)y ; (,/)(|)(0;mod[x;(#)y])_y ; y ] } [2;l] /5 7 11 2 3j I guess the above works

In response to @cillianreilly and @mchbrn-qIt seems, simple exec parse tree has a dual nature : It can act as a "c" and an "a" in ?[t;c;b;a] . It seems like a "c" here: ?[tab;til 10;(where;(>;`c2;16))] /Equivalent ?[tab;til 10;((&:);(>;`c2;16))] It s...

Where in the doc does it say a "where" is needed ? Similarly adding ";" is not necessary in the examples shown in docs. @SJT, Are these both cases of incomplete documentation ?

Thanks Matthew. "....all things executed in the session, not just sync calls....." Does this mean any call in for the same session could introduce a timeout (unknowingly) for ALL the other calls for the same session too ?
