Syntax

global a

global a b ... c

Description

Generates global variables or defines existing variables as global. If a variable does not exist, LabVIEW generates an empty matrix for that global. Use the global function to access and pass data between the LabVIEW MathScript Window and a MathScript Node or between two MathScript Nodes. The global function generates global variables in a separate context than the global variables in LabVIEW. For example, if you use the global function to generate the global variable a in MathScript, you also can create a different global variable a in LabVIEW.
