PUSH_INNER_ARRAY DST stack machine operator for array 'symbol_name' is not yet implemented Facility: DEBUG, VMS Debugger Explanation: The named array is unconstrained, and its subscript bounds live in different places at different points in the program's execution. This cannot be denoted using DEBUG Symbol Table (DST) features which this version of the debugger supports. User Action: Verify that you are using the latest releases of the compiler and debugger. Examine the nearest object code which references the variable and simulate the access algorithm by hand.
