It is used when we want to save space in the generated code. pragma Compiler_Unit_Warning; package System.Concat_4 is procedure Str_Concat_4 (R : out String; S1, S2, S3, S4 : String); -- Performs the operation R := S1 & S2 & S3 & S4. The bounds -- of R are known to be correct (usually set by a call to the -- Str_Concat_Bounds_5 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. procedure Str_Concat_Bounds_4 (Lo, Hi : out Natural; S1, S2, S3, S4 : String); -- Assigns to Lo..Hi the bounds of the result of concatenating the four -- given strings, following the rules in the RM regarding null operands. end System.Concat_4;
