imperative language
imperative
imperative programming

   <language> Any {programming language} that specifies explicit
   manipulation of the state of the computer system, not to be
   confused with a {procedural language}, which specifies an
   explicit sequence of steps to perform.

   An example of an imperative (but non-procedural) language is a
   {data manipulation language} for a {relational database
   management system}.  This specifies changes to the database
   but does not necessarily require anyone to specify a sequence
   of steps.

   Both contrast with {declarative languages}, which specify
   neither explicit state manipulation nor a sequence of steps.
