Just a gentle reminder to RTFM. The CLOSE() routine has a keyword
/ALL that does just what you want. You can also use /FILE to
selectively close units <= 99.
If you ever want to know which files are open, just use:
help, /files

Just for completeness: you can find out your open files with HELP,/FILES
This may help if you only want to close some files but not all, so you
don't have to rerun everything...
