On the Subject of the AMSCO CM
The numbers shown on screen 1 will be referred to as the AMSCO Key.
Take the length of the encrypted word and modulo it by 3 to determine your starting group number:
| 0 | 1 | 2 |
|---|---|---|
| If the sum of the alphabetic positions of the encrypted word is odd, use 1. Otherwise use 2. | 1 | 2 |
Create an X amount of groups, alternating between 1 - 2 dashes starting with the starting group number. Keep creating groups until the number of dashes equal to the length of the encrypted word. Place each group of dashes underneath the AMSCO Key so that it fits into the columns of the key in reading order.
If the Submit Button is white, follow the instructions under Encrypt Instructions. Otherwise follow the instructions under Decrypt Instructions.
