Parameter values are displayed in decimal unless the /HEX
    qualifier is specified. Note that ASCII values are displayed
    in ASCII by default.

    When parameter names are abbreviated all parameters whose
    names match the abbreviation are printed.

    For example, the SHOW GBL command displays the GBLSECTIONS,
    GBLPAGES, and GBLPAGFIL parameters.

    You can enter a period (.) to indicate that you want to work
    with the system parameter that was specified in the last SET
    parameter-name or SHOW parameter-name command.
