'''HQ9+''' is a [[joke programming language]] created by [[Cliff Biffle]] that consists of only four [[command (computing)|commands]], each represented by a single character: H, Q, 9, and +.  It is not [[Turing-complete]], but it is highly efficient at certain types of [[computer program|programs]].

* The <code>H</code> command prints out [[Hello world program|"Hello, world!"]]

HQ9+ is a joke; each command represents a common task that beginners are given when learning to program, or that programmers give themselves when learning a new [[programming language]].  A common exercise, for example, is to write a [[computer program]] that prints "Hello, world!".  There are some programming languages in which this is actually 
quite difficult; however, in HQ9+ the task is elementary, since the program "H" will accomplish the task. One of the hardest tasks in many programming languages is to write a quine, that is, a program which prints its own source code. However, in HQ9+, this is also trivial.
