8.10.2 END DO

The END DO statement is provided by the GNU Fortran language.

This statement is used in one of two ways:

• The Fortran 90 meaning, in which it specifies the termination point of a single DO loop started with a DO statement that specifies no termination label.
• The MIL-STD 1753 meaning, in which it specifies the termination point of one or more DO loops, all of which start with a DO statement that specify the label defined for the END DO statement.

  This kind of END DO statement is merely a synonym for CONTINUE, except it is permitted only when the statement is labeled and a target of one or more labeled DO loops.

  It is expected that this use of END DO will be removed from the GNU Fortran language in the future, though it is likely that it will long be supported by g77 as a dialect form.
