the current screen, or of the emulation class itself. The token to be interpreteted comes in as a machine word possibly accompanied by two parameters. Likewise, the assigned operations, come with up to two arguments. One could consider making up a proper table from the function below. The technical reference manual provides more informations about this mapping.*/void TEmuVt102::tau( int token, int p, int q ){//scan_buffer_report();//if (token == TY_CHR___()) printf("%c",p); else//printf("tau(%d,%d,%d, %d,%d)\n",(token>>0)&0xff,(token>>8)&0xff,(token>>16)&0xffff,p,q);
