B4P Reference

Introduction

The boolean data type takes two values which are reserved keywords: true and false. Boolean results are provided with comparisons and specific functions providing boolean return values.
Attention: The keywords are case-sensitive. True and TRUE are a string values, as well as 'true' and "false".

       echo(true, " / ", type(true));        // Boolean true

       echo(True, " / ", type(True));        // This is a string value (T is upper case.)

       echo(5 > 6, " / ", type(5 > 6));      // Boolean false 

       echo(true & false);                   // Logical AND

       echo(true | false);                   // Logical OR

true / boolean
True / string
false / boolean
false
true
