They do not guarantee that the update of terminals will happen before a dialog. They do not take advantage of nodes that do support flow-through parameters. Sequence structures are not ideal and should be used sparingly. Without flow-through parameters, such as error clusters and refnums, you can use sequence structures to the force execution order. The second frame cannot begin execution until everything in the first frame completes execution. Sequence structures are a structure with frames, where each frame executes in order. 4ĥ Sequence Structures Force Execution Order For example, the One Button Dialog function does not have an error cluster input or output. Not all LabVIEW nodes have flow-through parameters to ensure data dependency. Use flow-through parameters, such as refnums and error clusters, to control execution order when natural data dependency does not exist. Use error clusters and refnums to force order of execution. 3Ĥ Flow-Through Parameters Force Execution Order Any one of these tasks could happen first. Example: Nothing forces the execution order of these tasks. By default, LabVIEW does not force sequential programming. Many of the VIs you write accomplish sequential tasks.
