open-in-new
<p>A very high-level programming language (VHLL) is a <a href="/facts/Programming_language/cWTYbgWa">programming language</a> with a very high level of <a href="/facts/Abstraction_(computer_science)/hAnxmJle">abstraction</a>, used primarily as a professional programmer productivity tool. </p><p>VHLLs are usually <a href="/facts/Domain-specific_language/n18H1foD">domain-specific languages</a>, limited to a very specific application, purpose, or type of task, and they are often <a href="/facts/Scripting_language/8pF4ajBL">scripting languages</a> (especially extension languages), controlling a specific environment. For this reason, very high-level programming languages are often referred to as goal-oriented programming languages. </p><p>The term VHLL was used in the 1990s for what are today more often called <a href="/facts/High-level_programming_language/smjECUhx">high-level programming languages</a> (not "very") used for scripting, such as <a href="/facts/Perl/fx31kjlT">Perl</a>, <a href="/facts/Python_(programming_language)/YbuGqofa">Python</a>, <a href="/facts/PHP/vU6YRJX0">PHP</a>, <a href="/facts/Ruby_(programming_language)/BeYSaPSR">Ruby</a>, and <a href="/facts/Visual_Basic/7QMXM6fP">Visual Basic</a>. </p>
