Library /sys$common/syshlp/tcpip$sda.hlb TCPIP, Development Qualifiers, /LIST  *Conan The Librarian (sorry for the slow response - running on an old VAX)

   The /LIST qualifier is used to display the selected driver
   symbol table files with their link date and times.  This is
   most useful when the loaded driver doesn't exactly match one
   which is present in the build hierarchies.  The version
   closest can then be selected with the appropriate /ECO_LEVEL
   (or /NOECO_LEVEL) qualifier
