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

    The SHOW ALL command displays all data collection options,
    definitions and mode settings you have established. It also
    displays the name of the log file, the name of the performance
    data file, and information on all major mode settings. Entering
    SHOW ALL is the same as entering a number of more detailed SHOW
    commands.
