This coding system does not work so well for the Pick 4 game because it generates too many possibilities; there are just too many codes to consider. However, I can reduce the number of codes if I simplified the matrix to this:

If you prefer letters….

The MAXIMUM number of STRAIGHT Pick 4 numbers for a particular hot code will be 256 (4 x 4 x 4 x 4) for code BBBB or 2222. That is a lot of numbers to play…but the payout is $9,000 online for a $1 straight hit ($2,250 for a 0.25 cent straight hit). This means that one has 34 chances to play (or 17 days in a 2-draw per day state). So assuming one has the money, it can be worth the investment.
The BOX version of the codes will reduce the playlist – but this will still be profitable because repeating numbers or letters (example: AABC, ABCC, BBCC) will capture many doubles and double-doubles. However, the most important factor is reducing the number of codes; and this system will definitely do that. I will also be updating the Straight Positional Control program so that it accepts more digits per position (now it only accepts 3; it will accept all 10).

=======================
Which got me thinking…if I used this for the Pick 3 game, I would create a system with just 27 possible sets of STRAIGHT codes (3 x 3 x 3). The smallest set will have 27 straight numbers (3 x 3 x 3), some will have 36 straight numbers (3 x 3 x 4), others 48 (3 x 4 x 4) and the most a code will have is 64 straight numbers (4 x 4 x 4). There will only be 10 box codes, which will dramatically simplify the game:
111, 112, 113, 122, 123, 133, 222, 223, 233, 333
So I will put up these programs and test them out. I know this coding system will work better for the Pick 4 game; I will see if it works better for the Pick 3 game; or maybe I will use both systems. The programs for this ABC coding system will up soon.
