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 on a VAX platform, the first
    parameter matching the abbreviation is selected for display.
    No ambiguity checks are made. On an Alpha or I64 platform, all
    parameters whose names match the abbreviation are printed.

    For example, a specification of SHOW GBL on a VAX system displays
    only the GBLSECTIONS parameter. To display the GBLPAGFIL
    parameter, you must specify SHOW GBLPAGF (to avoid further
    ambiguity with the GBLPAGES parameter). On an Alpha or I64
    system, the same SHOW GBL command displays GBLSECTIONS, GBLPAGES,
    and GBLPAGFIL.

    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.
