:''This page describes the array datatype as defined by array languages. For the role of arrays in [[APL syntax]], see [[Array]].'' | |||
The distinguishing feature of APL and the array language family is its focus on '''arrays'''. In most array languages the array is the only first class datatype. While this sounds like a very strict model of language design, in fact it imposes no restrictions at all: any kind of data can be treated as a [[scalar]], or array with rank 0! | The distinguishing feature of APL and the array language family is its focus on '''arrays'''.

Some languages, despite deriving from APL, do not use APL-style arrays at all! Examples include [[K]] and [[I]], which only have vectors, and [[MATLAB]], which has true multidimensional arrays but usually treats data as matrices. Languages like K are usually considered part of the array language or APL family, but may or may not be considered array languages themselves. | Some languages, despite deriving from APL, do not use APL-style arrays at all!
