Selecting a subprogram
As you execute a script the current subprogram appears in the debugger window.
The Calls tab contains a list of the subprograms currently in the execution stack in order of execution, with the currently executing subprogram at the beginning of the list. Subprograms are listed as object: event, for example, Calculate_totals: CLICK.
If you select a subprogram from the list, its script appears in the debugger window. If you select the subprogram that is currently executing, the current pointer points to the statement about to be executed. If you select another subprogram, the current pointer points to the statement that calls the next subprogram in the stack.
