[MITgcm-support] FORTRAN binary read help.

[Michael Schaferkotter (Contractor)]

jody;

after writing out the data on a powerpc Mac using the MATLAB program

x=cos(1:100); ieee='l'; prec='real*8';
fid = fopen('HorStruct.bin','w',ieee); fwrite(fid,x,prec); fclose(fid);


the following fortran program on a Intel MacBookPro, successfully reads the data back in:

program testprog

       integer, parameter :: real8  = selected_real_kind(10)

       real(kind=real8), dimension(100) :: horStructWest

       open(unit=111,file="HorStruct.bin", status="old", access="direct", recl=100*8 ,action="read")
       read(unit=111,rec=1) horStructWest 
       CLOSE (unit=111)

       print *, horStructWest

endprogram testprog

i/m sure it/s not the only way.
