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

 disp-name

    Specifies a display to be extracted. You can use the wildcard
    character (*) in a display name. When using /ALL, do not specify
    a display name.

 file-spec

    Specifies the file to which the information will be written. You
    can specify a logical name.

    If you specify /SCREEN_LAYOUT to save the configuration of the
    screen, then the default specification for the file is PCA.PCAC
    in the Collector, PCA.PCAA in the Analyzer. Otherwise, the
    default file specification is PCA.TXT.
