Learning qsort

Trying to get my head around qsort.  Looks promising, and people I respect say it's the right answer.

Here is my practice piece:

* 2-columns (State & City)
o sort by State, up or down
o sort by City, up or down
* always maintain the original order of the "other" column.

That looks to me like I'll want _8_ procedures?  3 columns would need _16_ procedures?   Methinks I have badly misunderstood something and best stop and ask questions.

(I am using Jon's quite clear article as a learning guide. qsort: A Better SORTA <https://www.itjungle.com/2012/01/25/fhg012512-story02/> )
