The current scope location dictates where the PL/SQL Interpreter looks for local variables and parameters. It corresponds to the current execution location of one of the PL/SQL subprograms on the stack.
Each time a program unit's execution is interrupted (for example, by a debug action), the scope location is initialized to the execution location of the subprogram at the bottom of the stack.
Once execution has been interrupted, you can change the current scope location to another frame on the stack. This enables you to view local variables in another subprogram in the call chain.
