Loads the symbol records of a module in the current image into
    the run-time symbol table (RST) of that image.

                                  NOTES

       The current image is either the main image (by default) or
       the image established as the current image by a previous SET
       IMAGE command.

       By default, the debugger automatically loads symbols in a
       module as needed. As such, this behavior makes the use of an
       explicit SET MODULE command optional. For more information,
       see SET MODE DYNAMIC.

    Format

      SET MODULE  [module-name[, . . . ]]
