Hello, there,

I'm programming school projects at home, and later I upload and compile the
source code on the school's computer.  At home I use DJGPP in a Windows98
environment, and at school it's a Linux 2.4.14 OS.   Does anyone know of
simple preprocessor directives that can determine which OS the program is
compiled on?

For instance,

#if  MSDOS
    #DEFINE CLEAR system("clrscr")
#elif LINUX
    #DEFINE CLEAR  system("clear")
#endif

I would certainly appreciate anyone's reply.

ed.
