Use local variables for storing data relevant to the execution of the sequence, such as maintaining counts or holding intermediate values. You can pass local variables by value or by reference to any step in the sequence that calls a subsequence or any step that calls a code module that uses a module adapter. You can also access local variables from code modules of steps in the sequence using the TestStand API.

Note TestStand can pass data to VIs only by value. LabVIEW does not support passing data by reference. You can return a value as an indicator, which TestStand treats as a separate parameter.

View and edit the local variables in the Variables pane of the Sequence File window. Use the Value column in the Variables pane to modify string, numeric, and Boolean values.

You can create an unlimited number of local variables in a sequence.
