==Alternative Definition==
'''5GL''' or '''fifth-generation programming language''' is programming that uses a visual or graphical development interface to create source language that is usually compiled with a 3GL or 4GL language compiler. Microsoft, Borland, IBM, and other companies make 5GL visual programming products for developing applications in [[Java (programming language)|Java]], for example. [[Visual programming]] allows you to easily envision [[object-oriented]] programming class hiararchies and drag icons to assemble program components.<br />
==Regular Expressions==
The [[regexp]] syntax forms a ___domain-specific 5GL. Rather than defining an algorithm, the programmer specifies, by means of specialized syntax, a pattern to match text against. The regex pattern is compiled and run against text, returning the text desired by the programmer.
