I've tried this simple prog to encrypt a file using XOR

hehe.

didn't anyone tell you that you have to allocate memory before you can gets into it?

char *arg[4]; ...

gets(arg[1]);

man gets:

gets() reads a line from stdin into the buffer pointed to ^^^^^^^^^^^^^^^^^^^ by s until either a terminating newline or EOF, which it replaces with '\0'. No check for buffer overrun is per- formed (see BUGS below).

My guess is it's purely coincidental that your code worked on DOS.
