The Language of a P L vs a P A

K and c don't have true higher dimensional arrays, and they also don't have a rank operator. They do have the concept of rank, but i think the primary data structure is an array. The second thing is that k t b plus, the k language and cu language, come with an incredibly powerfula data base. And i think it specifically has like a ton of functionality for time series stuff, which obviously appeare on wall street is want to do.
