'''Dyalog APL''', or simply '''Dyalog''', is a modern APL in the [[APL2]] tradition, first released by British company [[Dyalog Ltd.|Dyadic Systems Ltd.]] (now Dyalog Ltd.) in 1983 for the Zylog Z80 processor (the name ''Dyalog'' is a portmanteau of ''Dyadic'' and ''Zylog''). Dyalog supports several platforms and interfaces with many languages and runtimes including native [[wikipedia:Shared library|shared libraries]], [[.NET]], the [[wikipedia:Java virtual machine|JVM]], [[wikipedia:R (programming language)|R]], and [[wikipedia:Python (programming language)|Python]]. It is actively developed and has introduced many new primitives and concepts to array programming. Major categories of features introduced to APL by Dyalog are [[tacit]] programming by allowing named [[derived function]]s and later [[train]]s, lexically-scoped functional programming using [[dfn]]s, [[namespace]]s and [[object-oriented programming]], and the addition of [[leading axis theory]] and the [[Rank operator]] to the [[nested array model|nested array]] paradigm.
