COBOL uses the STRING statement to concatenate string variables. MATLAB and Octave use the syntax "[x y]" to concatenate x and y. Visual Basic and Visual Basic .NET can also use the "+" sign but at the risk of ambiguity if a string representing a number and a number are together. Microsoft Excel allows both "&" and the function "=CONCATENATE(X,Y)".
String functions are used in computer programming languages to manipulate a string or query information about a string (some do both).. Most programming languages that have a string datatype will have some string functions although there may be other low-level ways within each language to handle strings directly.
The XML Schema Definition language provides a set of 19 primitive data types: [17] string: a string, a sequence of Unicode code points; boolean: a Boolean; decimal: a number represented with decimal notation; float and double: floating-point numbers; duration, dateTime, time, date, gYearMonth, gYear, gMonthDay, gDay, and gMonth: Calendar dates ...

The standard type hierarchy of Python 3. In computer science and computer programming, a data type (or simply type) is a collection or grouping of data values, usually specified by a set of possible values, a set of allowed operations on these values, and/or a representation of these values as machine types.

In computing, type introspection is the ability of a program to examine the type or properties of an object at runtime. Some programming languages possess this capability. Introspection should not be confused with reflection , which goes a step further and is the ability for a program to manipulate the metadata, properties, and functions of an ...
A string (or word [23] or expression [24]) over Σ is any finite sequence of symbols from Σ. [25] For example, if Σ = {0, 1}, then 01011 is a string over Σ. The length of a string s is the number of symbols in s (the length of the sequence) and can be any non-negative integer; it is often denoted as |s|.
PHP; VBScript; Tcl – server-side in NaviServer and an essential component in electronics industry systems; WebDNA – dedicated to database-driven websites; The above examples are particularly dedicated to this purpose. A large number of other languages, such as Erlang, Scala, Perl, Ring and Ruby can be adapted (for instance, by being made ...
