By default the scanner generated by Flex is not reentrant. This can cause serious problems for programs that use the generated scanner from different threads. To overcome this issue there are options that Flex provides in order to achieve reentrancy. A detailed description of these options can be found in the Flex manual. [13]
The formatting placeholders in scanf are more or less the same as that in printf, its reverse function.As in printf, the POSIX extension n$ is defined. [2]There are rarely constants (i.e., characters that are not formatting placeholders) in a format string, mainly because a program is usually not designed to read known data, although scanf does accept these if explicitly specified.

Spirit allows for both scannerless and scanner-based parsing. SBP is a scannerless parser for Boolean grammars (a superset of context-free grammars), written in Java. Laja is a two-phase scannerless parser generator with support for mapping the grammar rules into objects, written in Java.
In 2018, Palm Studios published a remake of the engine, written in C++ and using OpenGL. Skifree: 1991 2022 Arcade: Microsoft: In 2022 reconstructed C code was released.

For instance, if a subroutine for calculating the square root of a number is in page 3, one might have three lines of code 3.1, 3.2 and 3.3, and it would be called using Do part 3. The code would return to the statement after the Do when it reaches the next line on a different page, for instance, 4.1.
A newline (frequently called line ending, end of line (EOL), next line (NEL) or line break) is a control character or sequence of control characters in character encoding specifications such as ASCII, EBCDIC, Unicode, etc.
Generally lexical grammars are context-free, or almost so, and thus require no looking back or ahead, or backtracking, which allows a simple, clean, and efficient implementation. This also allows simple one-way communication from lexer to parser, without needing any information flowing back to the lexer.
