Hi Lajos,

I may need ~2000 folders (in a tree) to distribute my files..
openw, creates a file, but if the folder to be written doesn't exist,
IDL exists with an error..

So my quesiton is: "Is there a commend/way to create folder inside IDL-
script"? Or Should I do it
through a shell-script..

Best Regards,
Ray
