LabVIEW Tip: Speedy LUT

[AustinPeter]

If you need to create a quick and efficient Look up table (LUT) or item/tag list, then you  can utilise the efficient underlying code written for variant attribute lookup. An example of loading a string LUT into a variant (named “Variant LUT”) is shown below. The setting of the attributes is not particularly quick, however, and as soon as you have a few items in the list, this method is much much quicker than a “Search 1D Array”. Even with small list, this lookup is at least as efficient as a “Search 1D Array”.
NOTE the tag must be a string, but the lookup item can be of any type.
