Library /sys$common/syshlp/sysgen.hlb SHOW, Description  *Conan The Librarian (sorry for the slow response - running on an old VAX)

    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 platform, all parameters
    whose names match the abbreviation will be printed.

    For example, a specification of SHOW GBL on a VAX 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, the same SHOW GBL command
    will display 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] command.
