To clarify the clarification, there is no statement


                                                      DO ALLI = 1, N


in FORTRAN 77. All DO statements in FORTRAN 77 have a statement label, e.g.,


                                                      DO 10 ALLI = 1, N


The form without a statement label is an extension. I believe the most common
definition of this extension is in Mil. Std. 1753. The form without a
statement label is also contained in the proposed Fortran 90.
