fstat, file_info and file_test [message #35090]

Hello,

This appears to be the week for file questions.

I see that in the now distant past, my question has been asked here
before, but the answers were pre-IDL 5.4 when FILE_xxxxx routines appeared.

I would like to have a test that reports if the file is open - by simply
providing the filename. FSTAT almost does it, but I have to associate
the file with a LUN first. FILE_INFO and FILE_TEST each take the
filename as an argument (instead of the lun that FSTAT requires), but
neither test for 'openess'.

What I would like to have is a function similar to:

result = FILE_ISOPEN(filename)

that returns a 1 (for open) or a 0 (for closed). Or, perhaps better in
the long run, I'd like to see an /ISOPEN keyword added to FILE_TEST.

Any suggestions?

Thanks,
Ben
