I always use !DIR + sep + 'this_pref' where sep is defined correctly '\
or :'. For unix I usually use getenv('HOME')+'/'+'.this_pref'. Since
IDL includes no intrinsic (read portable) way to create directories, you
must use the one included by default in all IDL sessions. This can get
to be bothersome for a large collection of preference files, and
therefore it seems that the ability for IDL to create and check on the
existence of directories in a system-generic way would be valuable.
