Loops and Case Structures

Structures are graphical representations of the loops and case statements of text-based programming languages. Use structures on the block diagram to repeat blocks of code and to execute code conditionally or in a specific order.

Like other nodes, structures have terminals that connect them to other block diagram nodes, execute automatically when input data are available, and supply data to output wires when execution completes.

Each structure has a distinctive, resizable border to enclose the section of the block diagram that executes according to the rules of the structure.
