Challenge: Generate 24 in the X register / display

[Fred Lusk]

I shortened my generic DM-42 program again. Now it is 10 steps. This program takes any single-digit number sitting in the X-register (or any number, positive, negative, or zero, for that matter), makes three copies in the stack (putting the number in X into Y and Z also), then uses all three numbers to create the number 24.

01 LBL "T4"
02 ENTER
03 ENTER
04 +
05 +
06 SIGN
07 RCL+ ST X
08 RCLx ST X
09 N!
10 END

If you preload the stack with the same number in X, Y, and Z, then delete steps 02 and 03, which leaves an 8-step program.

The following program will take ANY number in the X-register and convert it to 24. It works like the previous program, but it's simpler because it only has to deal with one number.

01 LBL "TF"
02 SIGN
03 RCL+ ST X
04 RCLx ST X
05 N!
06 END
