Sample Code to Illustrate Problem and Workarounds

! Compile options needed: none

      integer i, j, k
      character*10 str /"123456789"/

      print *, 'should print: 1   3   5'
      read (str, '(T5,I1,T3,I1,T1,I1)') k, j, i
      print *, i, j, k           ! Prints 7  6  5

      print *, 'Work-around #1: only tab forward'
      read (str, '(T1,I1,T3,I1,T5,I1)') i, j, k
      print *, i, j, k

      print *, 'Work-around #2: use TL edit descriptor'
      read (str, '(T5,I1,TL3,I1,TL3,I1)') k, j, i
      print *, i, j, k

      end
