 As a GNU extension, @command{gfortran} allows hexadecimal constants to
 be specified using the X prefix, in addition to the standard Z prefix.
+BOZ literal constants can also be specified by adding a suffix to the string.
+For example, @code{Z'ABC'} and @code{'ABC'Z} are the same constant.
+
+The Fortran standard restricts the appearance of a BOZ literal constant to
+the @code{DATA} statement, and it is expected to be assigned to an 
+@code{INTEGER} variable.  @command{gfortran} permits a BOZ to appear
+in any initialization expression as well as assignment statements.
+
+The use of a BOZ literal constant to initialize a @code{REAL} variable will 
+lead to confusion.  A BOZ literal constant is converted to an
+@code{INTEGER} with the kind type with the largest decimal representation
+before a conversion to a @code{REAL} variable.  That is, one should not
+expect a bitwise copy of the BOZ literal constant to be assigned to the
+@code{REAL}.
