===Unique variants===

* [[AwkAWK]] uses the empty string: two expressions adjacent to each other are concatenated. This is called [[Juxtaposition (literary)|juxtaposition]]. [[Unix shell]]s have a similar syntax. [[Rexx]] uses this syntax for concatenation including an intervening space.

* [[C (programming language)|C]] (along with [[Python (programming language)|Python]] and [[Dart (programming language)|Dart]]<ref>{{Cite web |title=Built-in types |url=https://dart.dev/language/built-in-types/ |access-date=2025-07-22 |website=dart.dev |language=en}}</ref>) allows juxtaposition for string literals, however, for strings stored as [[Character (computing)|character]] [[Array data structure|arrays]], the <code>[[strcat]]</code> function must be used.

* [[COBOL]] uses the <code>STRING</code> statement to concatenate string variables.

* [[MATLAB]] and [[GNU Octave programming language|Octave]] use the syntax "<code>[x y]</code>" to concatenate x and y.

* [[Visual Basic]] and [[Visual Basic .NET]] can also use the "<code>+</code>" sign but at the risk of ambiguity if a string representing a number and a number are together.

* [[Microsoft Excel]] allows both "<code>&</code>" and the function "<code>=CONCATENATE(X,Y)</code>".
