Library /sys$common/syshlp/lse$clihelp.hlb SHOW, BUFFER, Qualifiers, /FULL  *Conan The Librarian (sorry for the slow response - running on an old VAX)

    Causes LSE to list all the information available about each
    indicated buffer, including associated input and output files,
    language, and all the buffer attributes that you can set, such as
    margins and text-entry mode.

    If you specify an explicit buffer, /FULL is the default.
