Help in fortran 77

  1. Dec 22, 2008 #1
    Hi, I have some doubts about how to open files in fortran 77.
    The file must to be inside some particular directory?
    Sorry about my english.

    If you are using Windows, try the following code. If you are using Unix or Linux, change the back-slash to slash, and use the appropriate directory name, for example:
    /usr/myname/f77/test.dat
    The status could be 'new', 'old', 'unknown', and there are other options.

    Code (Text):
    C      open(10, file='testopen.dat',status='unknown')
    C      open(10, file='..\testopen.dat',status='unknown')
           open(10, file='c:\proj\f77\testopen.dat',status='unknown')
    C      read(10,*)x
    C      read(10,*)y
    C      print *,x,y
    C      rewind 10
          write(10,*)10.0
          write(10,*)12.0
          print *,10.0,12.0
          stop
          end
