Get or set the Autopreallocate arrays and strings setting on VIs. This is used by the FPGA module to optimize array and string operations by forcing LabVIEW to preallocate memory at compile time rather than dynamically allocating memory at run time.

This property is similar to the Autopreallocate arrays and strings checkbox on the Execution Page of the VI Properties dialog box.
