In the early 1980's I used a cross reference and a hex dump to find the value of FORTRAN variables at the time the program crashed. numerist at aquaporin4 dot com Using DDT under TOPS-10 or dbx under Unix, or gdb under Linux... one can find the value of variables when the program "dumped core". This obviated the need for a cross reference. -- numerist at aquaporin4 dot com
