Introduction
Text inside quotation marks allows practically all characters except the same single quotation mark symbol inside the text.
If this is needed, you put the text inside double quotation marks instead.
Text inside single quotation marks can be used for
- String values
- Variable names
- Table names
Rules
- Use single quotation marks (apostrophes) ' ... ' to enclose the text.
- Inside the quotation marks, all characters are fine, except the single quotation mark which delimits the text.
- All white spaces, including multiple consecutive spaces preserved.
- Example 1: 'Hello World' is not equal to 'Hello World'
- Example 2: 'Hello World' is not equal to ' Hello World '
- The text must fit on the same line.
- Exception: Use multi-line text using 3 consecutive quotation marks ''' (apostrophes) as delimiatersto formulate a text requiring multiple lines.
- Reserved keywords inside quotation marks are treated as text, e.g. 'true'.
- Various functions and comparisons support wildcard symbols
- Example 1: ABC = 'A*' returns true.
- Character entities like € or € for the EURO symbol € are supported. They are converted quasi at compile time to target characters.
- If the text is assigned to B4P variables or used inside expressions, then the variable assumes the type string and subtype softquoted string.
Examples
echo( 'Hello World' );
echo( ' Hello World ' );
echo( 'One + One' );
echo( '"In double quotation Marks"' );
echo( 'Price tags: € 10.00, € 10.00, € 10.00');
echo( '3 * 2 = 6' );
echo( 'A cheap way to continue on the next line' ); // Not recommended. Use '...', new line, '...' instead.
echo( new line, 'Line 1', new line, 'Line 2' ); Hello World
