I wrote a program in turbo c 3.0 and generated exe file.I copied that exe file to bsd system its not working.I came to know many reasons for that,different operating system(exe file was made in windows xp),turbo c cannot run on bsd.When i compiled using cc, it generates many errors.Does conio.h wont work in unix.Please let me know c compilers in unix environment(AIX,FREEBSD).can i run turbo c program in these compilers or i need to write a new program again?Thanks
