Re: Inconsitancies with 'INQUIRE'

Hi!

Erm... Sorry about that, I must have done something wrong before, now I
cannot reproduce it anymore: I now get the expected:
 T  YES YES
Filename:Test.txt:
/USER/philippe/Linux/Trial_And_Error/Fortran/GFortran/Inquire_ASCII
-rw-r-----  1 philippe mikrosim 1957 Oct 24 10:26 Test.txt
Test.txt: ASCII English text

Thanks a lot for pointing the right direction: my 'original' (i.e.:
not-reduced) problem (i.e.: reporting wrong for 'FORMATTED') can be
worked around by opening the file first.

Sorry about the wrong report, thanks a lot for helping me!
