-------------------------------------------------

  ! 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'

        print *, i, j, k

        print *, 'Work-around #2: use TL edit descriptor'
