(DM42) Lottery number generator programming

[psw]

Hello,

I am a sheer beginner of DM42 programming and interesting in a simple and useful program. Today I conceive something like the random number generator and show sets of integers on DM42/Free42 or HP-42S. In short, Linux command:

Code:

shuf -i 1-Y -n X

but I can't translate some parts.

By the way, this program would suggest horse racing Trio BOX or Lotto 7 (which I don't buy them so often.)
I wish you could help me to improve this idea.

Sample select 4 nominations from 18 horses. Y=18 X=4

--- X and Y register into R0 and R1
STO 00
R↓
STO 01

--- Random Number Part to store into Alpha memory
LBL "RNG"
DATE
TIME
x
SEED
RAN
RCLx 01
IP

-- Verify given numbers are not the same each other. (This is going to mess my brain)
x=y?
R↓
ASTO
GTO "RNG"

---Loop for X times
LBL "LOOP"
1
STO- 00
RCL 00
X≤0?
RTN
AVIEW
END

How you combine or improve these, I only know a little about 8-bit BASIC.
Thank you for reading and I look forward to hearing your great help.

Best regards,
