Overview
Inside B4P, every new line is counted as one character, regardless on which operating system B4P is running on.
The character code is ANSI / UNICODE 10 (line feed).
In B4P, the new line can be specified with:
- The plain text value new line. Specify it without quotation marks.
- Using the chr() function: chr(10)
- Using the character entity or &nl;. Text inside single quotation marks is required for this. The nl entity name is not an official HTML entity, but supported by B4P.
- Line breaks inside multi-line text values.
echo( Hello, new line, World, new line ); // Hello World on 2 rows, plus additional new line
echo( Hello, chr(10), World, chr(10) ); // New line represented as a character codes
echo( 'Hello World&#nl;' ); // New line represented as a character entities
echo( 'new line' ); // This is just text and not a new line symbol
echo( code( new line ) ); // Code 10, line feed
echo( 'Character count: ', new line{} ); // new line contains one characterHello

Loading and Saving Files
B4P is able to load text files containing both "carriage return + line feed" (CR+LF) characters common in Windows systems and "line feed only" (LF) common in UNIX/LINUX/MACOS systems. When saving contents to files, the new line symbol will be automatically saved as line-feed (LF) in UNIX / Linux / MacOS systems and carriage-return + line-feed (CR+LF) character pairs in Windows systems. The legacy Macintosh "carriage return only" (CR) used as line separator is not supported.
