A scripting language can be viewed as a domain-specific language for a particular environment; in the case of scripting an application, it is also known as an extension language. Scripting languages are also sometimes referred to as very high-level programming languages , as they operate at a high level of abstraction, or as control languages , particularly for job control languages on mainframes. The term "scripting language" is also used loosely to refer to dynamic high-level general-purpose languages , such as Perl ,  PowerShell , Python , and Tcl  with the term "script" often used for small programs up to a few thousand lines of code in such languages, or in domain-specific languages such as the text-processing languages sed and AWK.
