The following list contains syntax examples of how a range of element of an array can be accessed. In the following table: first – the index of the first element in the slice; last – the index of the last element in the slice; end – one more than the index of last element in the slice; len – the length of the slice (= end - first)
awk – used for text file manipulation. sed – parses and transforms text; SQL – has only a few keywords and not all the constructs needed for a full programming language [a] – many database management systems extend SQL with additional constructs as a stored procedure language
The user can search for elements in an associative array, and delete elements from the array. The following shows how multi-dimensional associative arrays can be simulated in standard AWK using concatenation and the built-in string-separator variable SUBSEP:
PowerShell is a task automation and configuration management program from Microsoft, consisting of a command-line shell and the associated scripting language. Initially a Windows component only, known as Windows PowerShell, it was made open-source and cross-platform on August 18, 2016, with the introduction of PowerShell Core. [9]
The program can create a complete text representation of any group of objects by calling these methods, which are almost always already implemented in the base associative array class. [23] For programs that use very large data sets, this sort of individual file storage is not appropriate, and a database management system (DB) is required. Some ...

Folds can be regarded as consistently replacing the structural components of a data structure with functions and values. Lists, for example, are built up in many functional languages from two primitives: any list is either an empty list, commonly called nil ([]), or is constructed by prefixing an element in front of another list, creating what is called a cons node ( Cons(X1,Cons(X2,Cons ...
