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)".
In the TeX typesetting program, left double quotes are produced by typing two back-ticks (``) and right double quotes by typing two apostrophes (''). This is a continuation of a typewriter tradition of using ticks for opening quotation marks; see Quotation mark § Typewriters and early computers.
Double quotes are not officially named in Lojban, but sometimes called lubu, following the same pattern as vowel letters, e.g. a = abu: Lojban uses the words lu and li’u, rather than punctuation, to surround quotes of grammatically correct Lojban. [49] Double quotes can also be used for aesthetic purposes.
The ditto mark is a shorthand sign, used mostly in hand-written text, indicating that the words or figures above it are to be repeated. [1] [2]The mark is made using "a pair of apostrophes"; [1] "a pair of marks " used underneath a word"; [3] the symbol " (quotation mark); [2] [4] or the symbol ” (right double quotation mark).
One of the oldest examples is in shell scripts, where single quotes indicate a raw string or "literal string", while double quotes have escape sequences and variable interpolation. For example, in Python , raw strings are preceded by an r or R – compare 'C:\\Windows' with r'C:\Windows' (though, a Python raw string cannot end in an odd number ...
Any field may be quoted (with double quotes). Fields containing a line-break, double-quote or commas should be quoted. (If they are not, the file will likely be impossible to process correctly.) If double-quotes are used to enclose fields, then a double-quote in a field must be represented by two double-quote characters.
A double vertical bar || or ‖ is the standard caesura mark in English literary criticism and analysis. It marks the strong break or caesura common to many forms of poetry , particularly Old English verse .
A spreadsheet's concatenate ("&") function is used to assemble a complex text string—in this example, XML code for an SVG "circle" element. In formal language theory and computer programming, string concatenation is the operation of joining character strings end-to-end. For example, the concatenation of "snow" and "ball" is "snowball".
