The System Dump Analyzer (SDA) allows you to inspect the contents
    of memory as saved in the dump taken at crash time or as exists
    in a running system. You can use SDA interactively or in batch
    mode. You can send the output from SDA to a listing file. You can
    use SDA to perform the following operations:

                    Assign a value to a symbol
                    Examine memory of any process
                    Format instructions and blocks of data
                    Display device data structures
                    Display memory management data structures
                    Display a summary of all processes on the system
                    Display the SDA symbol table
                    Copy the system dump file
                    Read global symbols from any object module
                    Search memory for a given value
                    Send output to a file or device
