The SET DEFINE command establishes a default qualifier for
    subsequent DEFINE commands. The parameters that you specify in
    the SET DEFINE command have the same names as the qualifiers for
    the DEFINE command. The qualifiers determine whether the DEFINE
    command binds a symbol to an address, a command string, a list of
    processes, or a value.

    You can override the current DEFINE default for the duration of
    a single DEFINE command by specifying another qualifier. Use the
    SHOW DEFINE command to identify the current DEFINE defaults.
