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

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

    Option       Usage

    UPPERCASE    Converts to uppercase.
    AS_IS        Leaves the case as specified in the source.

    Option2 controls whether or not external names greater than 31
    characters get truncated or shortened. Option2 values are:

    Option             Usage

    /NAMES=TRUNCATED   Truncates long external names to the first 31
    (default)          characters.
    /NAMES=SHORTENED   Shortens long external names.

                       A shortened name consists of the first 23
                       characters of the name followed by a 7-
                       character Cyclic Redundancy Check (CRC)
                       computed by looking at the full name, and
                       then a "$".

    The default is /NAMES=(UPPERCASE,TRUNCATED).

                                   NOTE

       The I64 C++ compiler has some additional encoding rules that
       are applied to symbol names after the ABI name mangling
       is determined. All symbols with C++ linkage have CRC
       encodings added to the name, are uppercased and shorten to
       31 characters if necessary. Since the CRC is computed before
       the name is uppercased, the symbol name is case-sensitive
       even though the final name is in uppercase. /NAMES=AS_IS and
       /NAMES=UPPER are not applicable to these symbols.

       All symbols without C++ linkage will have CRC encodings
       added if they are longer then 31 characters and
       /NAMES=SHORTEN is specified. Global variables with C++
       linkage are treated as if they have non-C++ linkage for
       compatibility with C and older compilers.
