mkdir?

Is there anyway to create a directory in your OS from within
IDL?
I keep running into problems using the SAVE function, when I
have forgotten to create the directory to which I am
saving.  I just want to add a line of code that checks if
the directory exists, and if it doesn't it makes the
directory.
BTW, I'm running on a Windows platform (your are welcome to
make fun of me at this point...)

Thanks,
