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

    Indicates how much information you want displayed. The /FULL
    qualifier causes LSE to display all the information available
    about each indicated routine, as specified by the current DEFINE
    ROUTINE command (see the list of qualifiers for the DEFINE ROUTINE
    command).

    If you specify an explicit name for the parameter, /FULL is the
    default.
