1004:   DEFINE command : '<symbol>' duplicated in <filename(modulename)>

     Explanation:  This message indicates that the name symbol defined
     in a DEFINE command, is also defined as public in the second module.
     This will occur if two procedures in separate .OBJ or .LIB files have
     the same name.  The first one found is the one which is linked into the
     program, and the second one is ignored.
