Syntax

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
ByteBoolvalue anywhere you can use aBoolean. It is most useful when interfacing with C and C++, where any non-zero integer is consideredTrue.WordBoolandLongBoolare similar toByteBool, but they have different sizes.
