{{Main|Function styles}}
Dialects offer a variety of ways to create [[function]]s and [[operator]]s. The three major branches are [[defined function]]s, which use a header declaring the function and argument names, [[anonymous function]]s such as [[dfn]]s, which also consist of a list of statements but have no header and use fixed argument names, and [[tacit programming|tacit function]]s, which are created by manipulating existing functions with no reference to [[argument]]s.
Defined functions were the dominant form for most of APL's history, with only some niche forms based on [[direct definition (notation)|direct definition notation]] appearing in the 1980s: the [[direct definition (operator)|direct definition operator]] in [[NARS]] and a library to translate this notation to defined functions in [[SHARP APL]]. [[Function assignment]], a necessary feature for tacit programming, began to appear in the 1980s, such as in [[Dyalog APL]] version 4.0 in 1986. However, [[train]]s, which make larger-scale tacit programming feasible, were not introduced to APL until around 2010. Dyalog's [[dfn]]s were introduced in 1996 to slow initial adoption; nearly all new dialects of the 2010s and later support a similar syntax. Because of the widespread use of dfns, several of these dialects no longer support a traditional function definition notation.

The following table shows support for various APL features: nesting either with [[box]]es or the [[nested array model]], [[defined function]]s or similar syntax, [[control structure]]s, [[dfn]]-style anonymous functions, [[tacit]] programming, particularly with [[train]]s, [[complex number]]s, arbitrary-precision integers, [[Unicode]] support, and [[namespace]]s or a similar encapsulation feature. The precise syntax and capabilities of these features might differ between dialects that support them.

Dialects included in the first row include [[APL\360]], [[APL\1130]], [[APL*PLUS]] before II, [[APL/700]], [[APL.SV]], [[APL 5100]], [[MCM/70]], [[VS APL]], [[APL\3000]], and [[Aplette]]. [[Extended Dyalog APL]] and [[Dyalog APL Vision]] have the same feature-set as [[Dyalog APL]].

Dates for [[APL+Win]] include those for APL*PLUS. [[Extended Dyalog APL]] and [[Dyalog APL Vision]] have the same feature set as [[Dyalog APL]].
