This is not completely true.  The most-used form of a loop construct in 
Fortran certainly is the following:

DO I = 1, N
.... <loop body>
ENDDO

but it is perfectly legal (in Fortran 95, i.e., the language that's 
covered by gfortran) to write:

DO
    IF (condition) EXIT
... <loop body>
ENDDO

or

DO WHILE (condition)
... <loop body>
ENDDO

Hope this helps,
