" *   TOPCODE stands for Target OPCODE; prefix is TOP.\n\
 *\n\
 *   typedef (enum) TOP\n\
 *      Contains all the target opcodes.  Their names have the form\n\
 *      TOP_<name>.\n\
 *\n\
 *   typedef mTOP\n\
 *      The smallest integer type that can contain all values of a TOP,\n\
 *      including TOP_UNDEFINED -- useful for conserving space in tables.\n\
 *",
" *   const TOP TOP_UNDEFINED\n\
 *      Useful value guaranteed not to be a valid TOP.\n\
 *\n\
 *   const int TOP_count\n\
 *      Gives the number of topcodes.\n\
 *\n\
 *   const char* TOP_Name(TOP topcode)\n\
 *      Returns an assembler style name for the given TOP.\n\
