# How to do code If Random(1, 50, 1) = 5,10,15,20,25,30,35,40,45, OR 50?

## Recommended Posts

Hello,

I'm trying to find the best way to generate a random number between, for example, 1 and 50, but have the code execute only when one of the randomly generated numbers is one of a chosen subset of numbers.

I can't quite work out hos to do it without having to do a big batch of If Else.

I was hoping to find a way to arrange the syntax something like this:

\$i = Random(1, 50, 1)

If \$i = (5,10,15,20,25,30,35,40,45, OR 50) Then

;do stuff

EndIf

Thanks for any ideas.

Okay, Thank you jchd, I see what you mean, when I use those kinds of numbers that are divisible like that, but what if I had numbers like:

\$i = Random(1, 373, 1)

If \$i = (1, 17, 67, 84, 111, 152, 201, 297, 330, OR 341) Then

;do stuff

EndIf

Thanks for any other ideas.

try loading values into an array, and selecting index at random:

```Global \$array[10] = [1, 17, 67, 84, 111, 152, 201, 297, 330, 341]

\$random = \$array[Random(0,UBound(\$array) - 1,1)]

MsgBox(0,"",\$random)```

One more suggestion:

```\$i = Random(1, 50, 1)
Switch \$i
Case 5,10,15,20,25,30,35,40,45,50
;do stuff
Case Else
;do other stuff
EndSwitch```

;do stuff

EndIf

Then, the simplest and fastest I can think of is:

```\$i = Random(1, 373, 1)
Switch \$i
Case 1, 17, 67, 84, 111, 152, 201, 297, 330, 341
;do stuff
Case Else
; do else case (optional)
EndIf```

Thanks so much jchd and zorphnog for the Switch Case idea.

Yes, that's what I was hoping for. Very nice!

Thanks also andybiochem for the arrays idea. I'll check that too, but I'm not familiar with arrays yet.

So this kind of thing works:

```\$i = Random(1, 100, 1)
Switch \$i

Case 1 To 50
\$msg = "1 to 50"

Case 51, 52
\$msg = "51,52"

Case 53 To 100
\$msg = "53 to 100"

Case Else
\$msg = "Case Else"

EndSwitch

MsgBox(0, Default, \$msg)```

Thanks again!
