To import a library is a way to read external, possibly compiled, routines, programs or packages. C and C++ preprocessor: The string is ended normally and continues by starting with a quote on the next line.TUTOR: Lines starting with a tab (after any indentation required by the context) continue the previous command.COBOL: String constants may be continued by not ending the original string in a PICTURE clause with ', then inserting a - in column 7 (same position as the * for comment is used.).Fortran 77: A non-comment line is a continuation of the previous non-comment line if any non-space character appears in column 6.Some form of inline comment serves as line continuation AutoHotkey: Any expression operators except ++ and -, as well as a comma or a period īackslash as first character of continued line.Operator as first character of continued line Ruby: left parenthesis, left square bracket, or left curly bracket.Batch file: starting a parenthetical block can allow line continuation.Left bracket delimiter as last character of line Contrast this with an inline comment, which extends until the first subsequent newline.)Ĭomma delimiter as last character of line including) the first subsequent newline character. (In essence, it begins a comment that extends through (i.e. MATLAB: The ellipsis token need not be the last characters on the line, but any following it will be ignored.JavaScript – only within single- or double-quoted stringsĮllipsis (as three periods–not one special character).Fortran 90, Fortran 95, Fortran 2003, Fortran 2008.JavaScript – Lines terminate with semicolon (which may be inferred).Whitespace – Languages that do not need continuations Line continuation is generally done as part of lexical analysis: a newline normally results in a token being added to the token stream, unless line continuation is detected. Semicolon separated (semicolon termination is allowed) Newline terminates line-scope, the closest to a "statement" that M has.Ī space separates/teminates a command, allowing another command to follow.Ĭomma separated (conjunction), semicolon separated (disjunction), period terminated (clause) Whitespace separated (semicolon optional) Semicolon separated (but sometimes implicitly inserted on newlines) Haskell (in do-notation, when braces are used) Semicolon separated (inserted by compiler) Whitespace separated, sometimes period separated, optionally separated with commas and semi-colons. In such languages, it allows a single statement to span more than just one line. "Line continuation" is a convention in line-oriented languages where the newline character could potentially be misinterpreted as a statement terminator. Languages that interpret the end of line to be the end of a statement are called "line-oriented" languages. A statement terminator is used to demarcate the end of an individual statement. When the Programming Languages (usually Algol descendants) has statements they typically have conventions for:Ī statement separator is used to demarcate boundaries between two separate statements. TUTOR (2 + 3)(4 5) $$ note implicit multiply operator.Suffix, postfix, or Reverse Polish notation Programming language expressions can be broadly classified into four syntax structures:
