LogiSwift tracks packages and flags them for different delivery regions using their tracking codes.

This is pseudo-code for an algorithm that routes packages based on the first character of their tracking code.

1 IF (code[0] >= "A" AND code[0] <= "H") THEN
2     SEND "Region East" TO DISPLAY
3 ELSE
4     IF (code[0] >= "I" AND code[0] <= "P") THEN
5         SEND "Region West" TO DISPLAY
6     ELSE
7         IF (code[0] >= "Q" AND code[0] <= "Z") THEN
8             SEND "Region South" TO DISPLAY
9         ELSE
10            SEND "Invalid tracking code" TO DISPLAY
11        END IF
12    END IF
13 END IF
