JavaScript – only within single- or double-quoted strings; Vimscript as first character of continued line; Backtick. PowerShell; Hyphen. SQL*Plus; Underscore. AutoIt; Cobra; Visual Basic; Xojo; Ellipsis (three dots) MATLAB: The ellipsis need not end the line, but text following it is ignored. [5]
The parsing word ." (dot-quote) reads a double-quote delimited string and appends code to the current definition so that the parsed string will be displayed upon execution. The space character separating the word ." from the string Hello, World! is not included as part of the string. It is needed so that the parser recognizes ." as a Forth word.
In computer science, an operator-precedence parser is a bottom-up parser that interprets an operator-precedence grammar.For example, most calculators use operator-precedence parsers to convert from the human-readable infix notation relying on order of operations to a format that is optimized for evaluation such as Reverse Polish notation (RPN).
The comma operator separates expressions (which have value) in a way analogous to how the semicolon terminates statements, and sequences of expressions are enclosed in parentheses analogously to how sequences of statements are enclosed in braces: [1] (a, b, c) is a sequence of expressions, separated by commas, which evaluates to the last expression c, while {a; b; c;} is a sequence of ...
C# (/ ˌ s iː ˈ ʃ ɑːr p / see SHARP) [b] is a general-purpose high-level programming language supporting multiple paradigms.C# encompasses static typing, [16]: 4 strong typing, lexically scoped, imperative, declarative, functional, generic, [16]: 22 object-oriented (class-based), and component-oriented programming disciplines.
Note the formula on the dot-matrix line above and the answer on the seven-segment line below, as well as the arrow keys allowing the entry to be reviewed and edited. This calculator program has accepted input in infix notation, and returned the answer , ¯. Here the comma is a decimal separator.
Predictive parsing is possible only for the class of LL grammars, which are the context-free grammars for which there exists some positive integer k that allows a recursive descent parser to decide which production to use by examining only the next k tokens of input.
Symbol-specific names are also used; decimal point and decimal comma refer to a dot (either baseline or middle) and comma respectively, when it is used as a decimal separator; these are the usual terms used in English, [1] [2] [3] with the aforementioned generic terms reserved for abstract usage.
