The Set Step

Continue the aa.aef script by dragging a Set step from the General palette to the Design pane, and dropping it over the second Create Container Prompt step.

Then configure the Set step to set the value of prefixPrompt to P[], which means it is empty.

This script uses this Set step to return callers to the MainMenu Label step to listen to menu options again, in order to clear this prompt of values that the script may have previously assigned.
