Labelling Networks
You can modify the usual order of execution of networks through a jump statement, which transfers the program control to a labelled network. To assign a label to a network, double-click the raised grey button on the left, which bears the network number.This causes a dialog box to appear, where you can type the label you want to associate with the selected network.
If you click OK, the label is printed in the top left-hand corner of the selected network.
