In Debugger one can see at any point what was the exact path to the current point, by using the Call Stack menu option. For batch operations we need sometimes this information, in order to make decisions or to debug some problems.
For a Uniface developer: - Can check if the current code is being executed from a specific operation and thus do X or from a different one an should do Y. - When a bug was reported and the developer wants to trace the leading code.
May reduce time needed for batch bugs to be solved. May make it easier to distingish between different situations. Since it allready exists on Debugger, may be not to complicated to develop.
