false Value

false (value)

The false value is a boolean "zero". It is the only alternative of the boolean true. Data and Methods can use the value false as a test or flag value.

Examples

Suppose we want to attach the image pointer image to a CImage object I. The following script fragment tests whether Attach was successful:

bSuccess = I:Attach( image )	-- returns true if image is attached.
if bSuccess == false then Exit() end	-- Exit if bSuccess is false

Alternatively, the same result may be obtained by simpler, more compact code that does not test against false:

bSuccess = I:Attach( image )	-- returns true if image is attached.
if not bSuccess then Exit() end	-- Exit if bSuccess is false
