Use the Stack window to display the chain of subprograms from the initial execution point to the currently executing subprogram.
To view stack frames:
Each stack frame is identified by a name and line number in one of the following formats:
ModuleName.ProgramUnitName::LineNumber
ModuleName.TriggerName (BlockName.ItemName)::LineNumber
ModuleName.PackageName.ProgramUnitName::LineNumber
SchemaName.StoredProgramUnitName::LineNumber
The line number represents the current execution location in a stack frame. The current execution location in the topmost stack contains the next statement to be executed when the application resumes running.
