Controls how the LabVIEW compiler performs certain operations and, in some cases, increases memory and VI efficiency. Use the In Place Element structure when you operate on a data element within an array, cluster, variant, or waveform without requiring the LabVIEW compiler to copy data values and maintain those values in memory. You also can use this structure to operate on any data type that you want to maintain within the same data space in memory. Right-click the border of the structure and select the border node that matches the operation you want to perform.

Right-click the border of the In Place Element structure and select from the following nodes to add to the structure border:

You can right-click a node and select Mark As Modifier to indicate the LabVIEW modifies the data you wire to the node, even if the block diagram does not indicate a modification of data occurs. The Mark As Modifier option is useful when you work with dynamic dispatch terminals. While the parent implementation of a dynamic dispatch subVI might not modify the data wired to the node, a child implementation might modify the data. Using the Mark As Modifier option then optimizes performance by minimizing the number of copies of the data LabVIEW creates.
