Sure, I will. Meanwhile, I have one more question with wine. Is it possible to run and compile FORTRAN77 programs in wine? Because my attempts e.g. me@linux:~/Documents/FORTRAN> wine list.com end as Code: wine: Unhandled page fault on write access to 0x00786f66 at address 0x7bc48b66 (thread 0021), starting debugger... err:seh:raise_exception Unhandled exception code c0000005 flags 0 addr 0x7bc49dcb The same holds with another program me@linux:~/Documents/FORTRAN/Programs> wine HOR-04.EXE Code: wine: Unhandled page fault on write access to 0x00786f66 at address 0x7bc48b66 (thread 0021), starting debugger... err:seh:raise_exception Unhandled exception code c0000005 flags 0 addr 0x7bc49dcb
