languages, however, a syntax error may be detected during program execution, and an interpreter's logic error error messages might not differentiate syntax errors from errors of other kinds. Unfortunately there is some disagreement as to just syntax error grammar what errors are "syntax errors". For example, some would say that the use of an uninitialized variable's value in Java code is a syntax error, but many others would disagree[1][2] and would classify this

as a (static) semantic error. In 8-bit home computers that used BASIC interpreter as their primary user interface, the SYNTAX ERROR error message became somewhat notorious, as this was the response to any command or user input the interpreter couldn't parse. A syntax error may also occur when an invalid equation is entered into a calculator. This can be caused, for instance, by opening brackets without closing them, or

less commonly, entering several decimal points in one number. In Java the following is a syntactically correct statement: System.out.println("Hello World"); while the following is not: System.out.println(Hello World); The second example would theoretically print the variable Hello World instead of the words Hello World. However, a variable in Java cannot have a space in between, so the syntactically correct line would be System.out.println(Hello_World). A compiler will flag a syntax error when given source code that does not meet the requirements of the language grammar. Type errors (such as an attempt to apply the ++ increment operator to a boolean variable in Java) and undeclared variable errors are sometimes considered to be syntax errors when they are detected at compile-time. However, it is common to classify such errors as (static) semantic errors instead.[2][3][4] See also[edit] Tag soup References[edit] ^ Issue of syntax or semantics? ^ a b Semantic Errors in Java ^ Aho, Alfred V.; Monica S.

and are caused by grammatically incorrect statements. Typical errors might be an illegal character in the input, a missing operator, two operators in a row, two statements on the same line with no intervening semicolon, unbalanced parentheses, a misplaced reserved word, etc. Semantic errors occur during the execution of the code, after it has been parsed as grammatically correct. These have to do not with how statements are constructed, but with what they mean. Such things as incorrect variable types or sizes, nonexistent variables, subscripts out of range, and the like, are semantic errors. Basis is a single-pass parser, that is, it looks at its input only once. It also is a one-look ahead parser, meaning that at the most it is never looking more than one symbol ahead of the current context. By the time a syntax error has been detected, it is likely that a lot of the context information to the left of the error has already been lost. The diagnostic information that Basis gives attempts to be as useful as possible, but because of the very limited context information available, it is far from perfect. Semantic errors are often possible to diagnose more precisely. We have attempted to make the semantic error information supplied as useful as possible. Sometimes some of the information is only useful to someone familiar with the internals of Basis; but we hope that in most cases it will help you find your error.
