In 2017 and 2018 the terminology used to describe Kx technology was reviewed and revised to prefer terms in general use for concepts common with other programming languages, and to describe adverbs more clearly.
The review deprecated and replaced these terms:
|verb||operator or keyword|
|element of a list||item of a list|
In contrast, to reflect the key roles played by values, iterators and the Apply/Index operator
|dimensions (of an array)||rank|
|valence (of a function)||rank|
