It is this latter version, which has some syntax differences from the first as well as support for the Apple II high-resolution graphics modes, that most people mean by the term " Applesoft.

Another way of putting the argument is to say computational computer programs can pass the Turing test for processing the syntax of a language, but that semantics cannot be reduced to syntax in the way Strong AI advocates hoped: processing semantics is conscious and intentional because we use semantics to consciously produce meaning by what we say.

Context-free languages are the theoretical basis for the syntax of most programming languages.

It is extensible through standard features such as Lisp macros ( compile-time code rearrangement accomplished by the program itself ) and reader macros ( extension of syntax to give special meaning to characters reserved for users for this purpose ).

The phonetics, phonology, morphology, syntax and lexicon for most of Canada are similar to that of the Western and Midland regions of the United States.

The syntax of CLU was based on ALGOL, then the starting point for most new language design.

For instance, here is the CLU syntax for a cluster that implements complex numbers:

Many high-level programming languages, and some higher-level assembly languages, such as MASM, on the other hand, have special syntax or other built-in support for certain data structures, such as vectors ( one-dimensional arrays ) in the C language or multi-dimensional arrays in Pascal.

A common misconception holds that a non-validating XML parser does not have to read document type declarations, when in fact, the document type declarations must still be scanned for correct syntax as well as validity of declarations, and the parser must still parse all entity declarations in the internal subset, and substitute the replacement texts of internal entities occurring anywhere in the document type declaration or in the document body.

If the XML document type declaration includes any SYSTEM identifier for the external subset, it can't be safely processed as standalone: the URI should be retrieved, otherwise there may be unknown named character entities whose definition may be needed to correctly parse the effective XML syntax in the internal subset or in the document body ( the XML syntax parsing is normally performed after the substitution of all named entities, excluding the five entities that are predefined in XML and that are implicitly substituted after parsing the XML document into lexical tokens ).

When considering an appropriate syntax, it is important to note that Dublin Core concepts and semantics are designed to be syntax independent, are equally applicable in a variety of contexts, as long as the metadata is in a form suitable for interpretation both by machines and by human beings.

There is no official syntax for Loxian.

For example, EDLIN in early MS-DOS versions and 32-bit versions of Windows NT has a somewhat similar syntax, and text editors in many MUDs ( LPMud and descendants, for example ) use ed-like syntax.

* Keyword-based syntax in the ALGOL / Pascal tradition but separator-free, insofar as semicolons are optional, with operator syntax available for routines.

An upshot of this is that " setters " can, and normally do, implement the invariants for which Eiffel provides syntax.

Among the arguments scholars give for a later dating of the book are language and style ( i. e. the vocabulary and syntax as compared to the late Hebrew and Aramaic, which suggest that the book should be dated later ).

Many aspects of the syntax of Greek have remained constant: verbs agree with their subject only, the use of the surviving cases is largely intact ( nominative for subjects and predicates, accusative for objects of most verbs and many prepositions, genitive for possessors ), articles precede nouns, adpositions are largely prepositional, relative clauses follow the noun they modify, relative pronouns are clause-initial.

Pragmatics involves considerations that make reference to the user of the language ; semantics considers expressions and what they denote ( the designata ) abstracted from the language user ; and syntax considers only the expressions themselves, abstracted from the designata.

The syntax determines which collections of symbols are legal expressions in first-order logic, while the semantics determine the meanings behind these expressions.

Some programming languages delay evaluation of expressions by default, and some others provide functions or special syntax to delay evaluation.

Booleans ( called truthvalues in MUMPS ): In IF commands and other syntax that has expressions evaluated as conditions, any string value is evaluated as a numeric value, and if that is a nonzero value, then it is interpreted as True.

An unusual feature of its syntax was that expressions were constructed using the conventional infix operators, but all of them had the same precedence and evaluation went from left to right unless there were brackets.

Programming language syntax is usually defined using a combination of regular expressions ( for lexical structure ) and Backus – Naur Form ( for grammatical structure ).

* Concise syntax for expressions, declarations and statements-with permitted abbreviations.

When Polish notation is used as a syntax for mathematical expressions by interpreters of programming languages, it is readily parsed into abstract syntax trees and can, in fact, define a one-to-one representation for the same.

Some of these languages, including Perl, Ruby, AWK, and Tcl, integrate regular expressions into the syntax of the core language itself.

Most operator-precedence parsers can be modified to produce postfix expressions ; in particular, once an abstract syntax tree has been constructed, the corresponding postfix expression is given by a simple post-order traversal of that tree.

The term syntactic sugar was coined by Peter J. Landin in 1964 to describe the surface syntax of A Programming Language ( APL ) which was defined semantically in terms of the applicative expressions of lambda calculus.

These include morphological information, such as what prefixes or suffixes they take, and also their syntax – how they combine with other words and expressions of particular types.

The AIML pattern syntax is a very simple pattern language, substantially less complex than regular expressions and as such not even of level 3 in the Chomsky hierarchy.

First, it has been suggested that the ontological commitments of a theory cannot be discerned by analysis of the syntax of sentences, looking for ontologically committing expressions, because the true ontological commitments of a sentence ( or theory ) are restricted to the entities needed to serve as truthmakers for that sentence, and the syntax of even a regimented or formalized sentence is not a reliable guide to what entities are needed to make it true.

Similarly, statically checked, type-safe regular expressions or code generation may be added to the syntax and semantics of OCaml through macros, as well as micro-threads ( also known as coroutines or fibers ), monads or transparent XML manipulation.

However its syntax and matching abilities differs significantly from ones of ordinary regular expressions.

The syntax of second-order logic tells which expressions are well formed formulas.

RELAX NG compact syntax is a non-XML format inspired by extended Backus-Naur form and regular expressions, designed so that it can be unambiguously translated to its XML counterpart, and back again, with one-to-one correspondence in structure and meaning, in much the same way that Simple Outline XML ( SOX ) relates to XML.

* the syntax of a language is what the language looks like ( more formally: the set of possible expressions that are valid utterances in the language )

This means that conditions can be inlined into expressions, unlike with if statements, as shown here using C syntax:

The assignment syntax is unusual ; rather than using a let statement or an equals sign, TI-BASIC uses a right-arrow " STO " operator with the syntax: source → destination.

Users sometimes refer to its syntax as " FLWOR " ( pronounced ' Flower ') because the query may include the following clauses: ' for ', ' let ', ' where ', ' order by ' and ' return '.

The following example shows how to use Bison and flex to write a simple calculator program ( only addition and multiplication ) and a program for creating an abstract syntax tree.

As a result of the tokenizing process, programmers could not use any variable name that had the name of one of the BASIC commands ( e. g. a person could not use the name " SCORE " because the " OR " would invoke a disjunction operator, and " BACKGROUND " could similarly not be used because " GR " would invoke the low-resolution graphics system ; both would create syntax errors ).

MUMPS can be made more obfuscated by using the contracted operator syntax, as shown in this terse example derived from the example above:

This has the advantage of avoiding a classic C error of mistaking an assignment operator for an equality operator in conditions: is valid C code but causes a syntax error in Python.

Scheme's very simple syntax is based on s-expressions, parenthesized lists in which a prefix operator is followed by its arguments.

The updated IEEE 1076, in 1993, made the syntax more consistent, allowed more flexibility in naming, extended the type to allow ISO-8859-1 printable characters, added the operator, etc.

Objects were addressed using a syntax close to natural language, where objects were specified relative to the current card, or the operator was used to specify the absolute position of an object:.

In OCaml, only single assignment is allowed for variables, via the syntax ; however destructive update can be used on elements of arrays and strings with separate < code ><-</ code > operator, as well as on fields of records and objects that have been explicitly declared mutable ( meaning capable of being changed after their initial declaration ) by the programmer.

A nondeterministic choice operator can be added to the syntax.

Many programming languages that use C-like syntax feature a ternary operator,, which defines a conditional expression.

For example, in Prolog, the infix operator "< tt >:-</ tt >" is non-associative, so constructs such as "< tt > a :- b :- c </ tt >" constitute syntax errors.

If the operator is non-associative, the expression might be a syntax error, or it might have some special meaning.

In Prolog, the infix operator < tt >:-</ tt > is non-associative because constructs such as "< tt > a :- b :- c </ tt >" constitute syntax errors.

Groovy features not available in Java include both static and dynamic typing ( with the def keyword ), closures, operator overloading, native syntax for lists and associative arrays ( maps ), native support for regular expressions, polymorphic iteration, expressions embedded inside strings, additional helper methods, and the safe navigation operator "?.

In computer programming, is a ternary operator that is part of the syntax for a basic conditional expression in several programming languages.

GML is structurally similar to C-based languages in its use of code blocks, function calls, variable assignments, operator syntax, and so on.

As a guideline for constructing semantic theories, this is generally taken, as in the influential work on the philosophy of language by Donald Davidson, to mean that every construct of the syntax should be associated by a clause of the T-schema with an operator in the semantics that specifies how the meaning of the whole expression is built from constituents combined by the syntactic rule.

Algebraic syntax is achieved in C ++ through the use of operator overloading.

In 1976, he wrote an MIT AI Lab working paper about CGOL, an alternative syntax for MACLISP that he had designed and implemented based on his paradigm for top down operator precedence parsing.
