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.
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 |
