In the following example, the values of original list items \ucode{i} and \ucode{j} 
are retained on exit from the \kcode{parallel} region, while the private list 
items \ucode{i} and \ucode{j} are modified within the \kcode{parallel} construct.

In the following example, all uses of the variable \ucode{a} within the loop construct 
in the routine \ucode{f} refer to a private list item \ucode{a}, while it is 
unspecified whether references to \ucode{a} in the routine \ucode{g} are to a 
private list item or the original list item.

The following example demonstrates that a list item that appears in a \kcode{private} 
 clause in a \kcode{parallel} construct may also appear in a \kcode{private} 
 clause in an enclosed worksharing construct, which results in an additional private 
copy.
