How can I set that using the FILE_CHMODE command in IDL?
I have set

FILE_CHMOD, filename, U_WRITE=0, G_WRITE=0,O_WRITE=0

and I thought this should only create a readable file only. However,
when I gave this file to someone to test it the person was able to
modify the file without any problem. Any help is appreciated.

Thanks,
