'spawn' can do both of these

1. To check if a directory exists:
IDL> dir='/home/me/mydir'
IDL> spawn, 'ls -a '+dir, result

Now, check the length of RESULT[0]. If it is zero, then
DIR doesn't exist, otherwise DIR does exist.

2. To create a directory
IDL> spawn,'mkdir '+dir

This may not be elegant, but it works.
