 @cindex Hollerith constants
 
 GNU Fortran supports Hollerith constants in assignments, function
-arguments, and @code{DATA} and @code{ASSIGN} statements.  A Hollerith
-constant is written as a string of characters preceded by an integer
-constant indicating the character count, and the letter @code{H} or
-@code{h}, and stored in bytewise fashion in a numeric (@code{INTEGER},
-@code{REAL}, or @code{complex}) or @code{LOGICAL} variable.  The
-constant will be padded or truncated to fit the size of the variable in
-which it is stored.
