+<h4 class="subsection">5.1.2 Old-style variable initialization</h4>
+
+<p>GNU Fortran allows old-style initialization of variables of the
+form:
+</p><div class="smallexample">
+<pre class="smallexample">      INTEGER i/1/,j/2/
+      REAL x(2,2) /3*0.,1./
+</pre></div>
+<p>The syntax for the initializers is as for the <code>DATA</code> statement, but
+unlike in a <code>DATA</code> statement, an initializer only applies to the
+variable immediately preceding the initialization.  In other words,
+something like <code>INTEGER I,J/2,3/</code> is not valid.  This style of
+initialization is only allowed in declarations without double colons
+(<code>::</code>); the double colons were introduced in Fortran 90, which also
+introduced a standard syntax for initializing variables in type
+declarations.
+</p>
+<p>Examples of standard-conforming code equivalent to the above example
+are:
+</p><div class="smallexample">
+<pre class="smallexample">! Fortran 90
+      INTEGER :: i = 1, j = 2
+      REAL :: x(2,2) = RESHAPE((/0.,0.,0.,1./),SHAPE(x))
+! Fortran 77
+      INTEGER i, j
+      REAL x(2,2)
+      DATA i/1/, j/2/, x/3*0.,1./
+</pre></div>
+
+<p>Note that variables which are explicitly initialized in declarations
+or in <code>DATA</code> statements automatically acquire the <code>SAVE</code>
+attribute.
+</p>
