/sys$common/syshlp/helplib.hlb CC, /NAMES  *Conan The Librarian (sorry for the slow response - running on an old VAX)

     /NAMES=(option1,option2)
     /NAMES=(UPPERCASE,TRUNCATED) (D)

  Option1 converts all definitions and references of external symbols
  and psects to the specified case:

   o  /NAMES=UPPERCASE (default) converts to uppercase.

   o  /NAMES=LOWERCASE converts to lowercase.

   o  /NAMES=AS_IS leaves the case unchanged.

  Option2 controls whether or not long external names greater than 31
  characters get truncated or shortened:

   o  /NAMES=TRUNCATED (default) truncates long external names

   o  /NAMES=SHORTENED shortens long external names.

      A shortened name consists of the first 24 characters of the
      name followed by a 7-character Cyclic Redundancy Check (CRC)
      computed by looking at the full name.

  By default, the compiler issues a warning and truncates the name to
  31 characters.

  The /NAMES qualifier does not affect the names of the $CODE and
  $DATA psects.
