Each step or transition is identified by a number. A jump to a step is also identified by the number of the destination step. The SFC editor allocates a new number to each step or transition inserted in the chart.
To change the number of a step, transition or jump, select it and hit Ctrl+ENTER keys.
It is not possible to change the number of a step or a transition if its level 2 is currently open for editing. The number is used for identifying the step or transition in the level 2 editing window.
In compiler reports, a step is identified by its number prefixed by "GS". A transition is identified by its number prefixed by "GT".
