How about looking for the IDL startup file (providing you use an identical
name like idl_startup.pro everywhere -- or you query getenv('IDL_STARTUP'))
and put your preferences file in that same directory. I always dislike
cluttering my $HOME directory with "selfmade" files, and assuming a
hard-wired directory name for any users' IDL applications seems risky, too.
If you wish, you can download file_exist.pro and extract_path.pro from my web
page (see below); the first retrieves the fully qualified path for a file in
a list of directories (just pass !PATH here, so it will automatically be
platform dependent [pun intended]), and the latter cuts out the directory
portion of that full path. But you'll probably have something like this on
your own ...
Regards,
Martin.
