frecord-marker'

[Sébastien Rousseaux]

Hello
I need to read a fortran file generated with a 32 bits marker. This file was generated by a HPUNIX computer.
Actually I'am on a Linux computer and I manage to read the file in the right way using the option 'CONVERT'.
I use gfortran as a compiler.
I heard about the 'frecord-marker' option in using the compiler. I tryed to used it and I didn't saw any different in initialising it at 4 or 8. So I look on the net and saw this option doesn't work and instead of we have to use the option RECM=4 while we open the file.
So actualy my open function is like :
          OPEN ( UNIT=IUNIT,
     %          FILE=AC_NAME_FILE,
     %          FORM='UNFORMATTED',
     %          RECM='4',
     %          ACCESS='SEQUENTIAL',
     %          STATUS='OLD',
     %          CONVERT='SWAP',
     %          IOSTAT=IOS)

The problem I have is gfortran doesn't recognize RECM.
When I compile my project I have
gfortran -g  -I../inc  -DCN_RSIZE=4 -DCN_ISIZE=4  -frecord-marker=4 -fcray-pointer -ffpe-trap=overflow,zero,invalid -fconvert=big-endian   -c tvload.F
 In file tvload.F:223

     %          FORM='UNFORMATTED',                                    
                                                         1
Error: Syntax error in OPEN statement at (1)

I used
GNU Fortran (GCC) 4.1.2 20070626 (Red Hat 4.1.2-14).

Linux 2.6.18-53.el5 #1 SMP Wed Oct 10 16:34:02 EDT 2007 i686

I'm not at the moment on the mailing list. So please can you answer me in my own mail address.
Thank you very much for your help.
