--  This package contains a procedure for runtime concatenation of seven string
--  operands. It is used when we want to save space in the generated code.

     (R                          : out String;

   --  Performs the operation R := S1 & S2 & S3 & S4 & S5 & S6 & S7. The
   --  bounds of R are known to be correct (usually set by a call to the
   --  Str_Concat_Bounds_8 procedure below), so no bounds checks are required,
   --  and it is known that none of the input operands overlaps R. No
   --  assumptions can be made about the lower bounds of any of the operands.

   --  given strings, following the rules in the RM regarding null operands.
