This stuff is confusing because I don't use it enough.



Using the "QNial Language Definition.odt" manual, p24 : 
TWIG f A		deeply nested simple arrays of A
LEAF f A		deeply nested atoms of A

Using the "QNial Language Definition.odt" manual, p22 : 
mix A		   array formed by merging the first two levels of A, placing the axes of the top level first
A raise B	array containing arrays of items of B partitioned along axes so that the result has the first A axes of B 
A lower B	array containing arrays of items of B partitioned along axes so that the items have the last A axes of B 
A split B	arrays of items of B where the axes mentioned in A become the axes of the items of the result
A blend B	array of valence equal to valence of B plus the valence of an item of B obtained by merging axes of B according to axis numbers in A
content A	list of atoms of A in depth-first row-major order

keyStrsList is a list of items that themselves are lists of 3 elements 

Try 
qnial>  mix  keyStrsList  
>> perfect!!, I but I had already created keyStrsList

For "details" :
qnial>  3 lower details
>> nyet - this is for regular arrays with simple contents

qnial>  [first, second, last] details 
qnial>  mix details
>> nyet, but they look the same!??
qnial>  = details  (mix details)
o
qnial>  TWIG [first, second, third] details
qnial>  link details
qnial>  EACH [first, rest] link details 
qnial>  EACH first link details
>> great - pulls out FAQ titles
qnial>  EACH second link details
>> Tos 
qnial>  EACH third link details
>> CCs

Single expression to get all in one shot :
qnial>  EACH [first, second, third] link details
>> not quite
qnial>  link  EACH [first, second, third] link details
qnial>
>> Close!
qnial>  a :=  link  EACH [first, second, third] link details
qnial>  n :=  gage shape a 
qnial>  a_rows  :=  floor  (n / 3)
qnial>  b c d  :=  cols (a_rows 3  reshape a)
>> yes!  this is what I want!

Comprehensive expression : 
qnial>  
qnial>  
qnial>  
qnial>  
qnial>  
qnial>  




For HELPER_WCCI2020 :
	keyStrsList  TosList  CCsList  :=  cols  mix  details  ;
