[net.lang.f77] Free-form input in F77

   What I would recommend doing is, of course, a kludge. Read your data
lines into a CHARACTER variable, and then do internal file reads (which
can be repeated on the same line from different starting points as often
as desired) on the resulting line in core. Quick example:

      program analyz
      character*82 line
      open(unit=1,file='datafile')
      rewind 1
 10   continue
      read(1,100) line
 100  format(a)
      if (line(1:5).eq.'type1') then
c	code to process type 1
c     may include something like
c       read(line(6:82),200) int1,float1,int2
c200    format(i5,f8.2,i5)
      else if (line(1:5).eq.'type2') then
	 code to process type 2
      ......

      endif
      goto 10
      end

  What this does is only access the file once per line, as FORTRAN requires,
and then manipulate that line in-core. Something like this should solve
your problem.
