Copy the characters in @var{str} to the object file. You may specify more than
one string to copy, separated by commas. Unless otherwise specified for a
particular machine, the assembler marks the end of each string with a 0 byte.
You can use any of the escape sequences described in @ref{Strings,,Strings}.
+The variants @code{string16}, @code{string32} and @code{string64} differ from
+the @code{string} pseudo opcode in that each 8-bit character from @var{str} is
+copied and expanded to 16, 32 or 64 bits respectively. The expanded characters
+are stored in target endianness byte order.
+
+Example:
+@smallexample
+ .string32 "BYE"
+expands to:
+ .string "B\0\0\0Y\0\0\0E\0\0\0" /* On little endian targets. */
+ .string "\0\0\0B\0\0\0Y\0\0\0E" /* On big endian targets. */
