Delphi in a Nutshell

Name

WordBool Type

Syntax

type WordBool;

Description

The WordBool type is a logical type whose size is the same as the size of a Word. A WordBool value is False when its ordinal value is zero, and it is True when its ordinal value is any non-zero value. WordBool uses -1 as the ordinal value for True constants, e.g., WordBool(True).

Tips and Tricks

• You can use a WordBool value anywhere you can use a Boolean. It is most useful when interfacing with C and C++, where any non-zero integer is considered True.

• ByteBool and LongBool are similar to WordBool, but they have different sizes.
