I couldn't get it to compile and the documentation said it couldn't

forgot the quotes and of course I should know better than to rely on
the documentation.

 From the V5R3 ILE C/C++ Compiler Reference manual (page 54):

     #--pragma--map--(--name1--,--"--name2--"--)

     Specifies that the compiler is to replace the external symbol
     (that is used in your C source) "name1" with the external symbol
     "name2".  Case significance is preseved only for those systems
     that support case distinction for external symbols.

     The #pragma map directive supports library-qualified program
     names. See "linkage" on page 52 for more information.

I agree that this documentation is rather confusing. (In particular, the
reference to "linkage" is confusing and misleading.) But it does say
that it supports library-qualified program names.

I got it from here:

http://publib.boulder.ibm.com/infocenter/iadthelp/v6r0/index.jsp?topic=/com.
ibm.etools.iseries.pgmgd.doc/cpprog508.htm

"The program name that the ILE C/C++ program calls must be in uppercase. You
can use the #pragma map directive to map an internal identifier longer than
10 characters to an OS/400-compliant object name (10 characters or less) in
your program."

Says pretty clearly it must be an uppercase object name of ten characters or
less, which led me to believe that fully qualified wouldn't work.  This
wouldn't be the first time two IBM documents didn't agree.
