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
                 Send output to a file or device
                 Read global symbols from any object module
                 Search memory for a given value
