I don't understand. Why not do the logic within your IDL_STARTUP
file, in which case you can execute arbitrary IDL code? You would
modify David's JOURNAL_UNIQUE procedure to test that the file exists
before opening it, and if it does, append a unique suffix or whatever,
and then retest. No need for alias-nasties!

Good luck,
Craig
