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.
