\chapter{Fortran Restrictions on the \code{do} Construct}
\label{chap:fort_do}
\fortranspecificstart

If an \code{end do} directive follows a \plc{do-construct}  in which several 
\code{DO} statements share a \code{DO} termination statement, then a  \code{do} 
directive can only be specified for the outermost of these \code{DO} statements. 
The following example contains correct usages of loop constructs:

\fnexample{fort_do}{1f}

The following example is non-conforming because the matching \code{do} directive 
for the \code{end do} does not precede the outermost loop:

\fnexample{fort_do}{2f}
\fortranspecificend
