However, you can use the predefined package Ada.Strings.Fixed to
move the shorter string into the longer string.

The Ada Reference Manual describes the move procedure as:

procedure Move (Source : in String;
Target : out String;
Drop : in Truncation := Error;
Justify : in Alignment := Left;
Pad : in Character := Space);

Note that the package Ada.Strings is defined as:

package Ada.Strings is
pragma Pure(Strings);

Space : constant Character := ' ';
Wide_Space : constant Wide_Character := ' ';

Length_Error, Pattern_Error, Index_Error, Translation_Error :
exception;

type Alignment is (Left, Right, Center);
type Truncation is (Left, Right, Error);
type Membership is (Inside, Outside);
type Direction is (Forward, Backward);
type Trim_End is (Left, Right, Both); 
end Ada.Strings;
