However if I can do that, I may probably find where the bug is ( the program is about 2500 lines of c++ source code); I'm using AT&T C++ 2.0 on SunOS 3.5. When I compiling and linking the program, there is no error message. But when I execute it, I get the following error message in dbx signal ILL (illegal instruction) in cerror at 0x4e096 0x4e096: moveq #0x74,d1 I guess it is something wrong with the virtual function. Have you encountered this problem before ? Thanks in advance. send e-mail to zq@eecg.toronto.edu Qing
