Delphi in a Nutshell

Name

ByteBool Type

Syntax

type ByteBool;

Description

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

Tips and Tricks

• You can use a ByteBool 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.

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