Please, I have only a trivial question. In Monkey2 I can not use the RND command. Maybe it is used differently than in MonkeyX.

Result: Identifier ‘Rnd’ not found

Thanks in advance!

Monkey

Function shuffle() Local a1:Int a1=Rnd(1,17) Print (a1) End Function Main() shuffle() End

   Local a1:Int

   a1=Rnd(1,17)
   Print (a1)

End

Function Main()
   shuffle()
End

Do you import and use std?
Rnd is part of std module.
At the beginning of your code you should have:

Monkey

[crayon-5cba953788c6a396912716 inline="true" ] #Import "<std>" Using std..

#Import "<std>"
Using std..

I’m sorry, I’m trying to some basic principles

Work with arrays is not clear to me. This is syntactically correct, but does not fill the field? (Array index out of range)

Monkey

#Import "<std>" Using std.. Global x:Int[] Function shuffle() x[1]=10 End Function Main() shuffle() End

#Import "<std>"
Using std..

Global x:Int[]

Function shuffle()

   x[1]=10

End

Function Main()
   shuffle()
End

You need to create the array with new and specify how many:

Monkey

#Import "<std>" Using std.. Global x:=New Int[10] Function shuffle() x[1]=10 End Function Main() shuffle() End

#Import "<std>"
Using std..

Global x:=New Int[10]

Function shuffle()

   x[1]=10

End

Function Main()
   shuffle()
End
