Globals/locals metrics, available in the LabVIEW Professional Development System, appear in the VI Metrics window when you place a checkmark in the Globals/locals checkbox. The following metrics specify the global and local variables of a VI:
Global reads—Number of reads of global variables on the block diagram.
Global writes—Number of writes to global variables on the block diagram.
Local reads—Number of reads of local variables on the block diagram.
Local writes—Number of writes to local variables on the block diagram.
