Introduction to reserved keywords
B4P has only six reserved symbols which must be specified as plain text using lower-case letters and without quotation marks.
| Reserved Keyword | Meaning | Description |
|---|---|---|
| tab | Tabulator | Converts to a tab character (ANSI and UNICODE 9) |
| new line | Line Break | Represented as ANSI and UNICODE 10. Under Windows, Carriage Return symbols are added before line feed symbols when saving contents in files. |
| escape | Escape chracter | Converts to an escape character (ANSI and UNICODE 27) |
| true | Boolean true | 'true' as boolean type and not as text |
| false | Boolean false | 'false' as boolean type and not as text |
| else | 'else' in code syntax | To be used in association with if, switch and other control flow functions. |
Different from other languages, flow control features like if() and while() are function names and not reserved keywords.
Alternatively to using tab, you consider special console output characters such as &tab20; to advance to a specified column.
echo( type(true) );
echo( 1, tab, 2, tab, 3 );
echo( 1st line, new line, 2nd line );
echo( true = false ); // Outputs 'false' (Boolean comparison)boolean
1 2 3
1st line
