selecting positive values

[mac ye]

I got a problem in filtering positive values from a data set.

background:
A is a data set with pos and neg values. and I want to selet all the positive values and set all negative values to 0
so I create a data set B with same number of colums and initial value as 0

I wrote a script in a function like this:

Dim i
For i=0 To 8000 Do
If A < 0 Then
B==A
End
End

But it returns "no value"
Would you please give me an example for this?

You have to use = instead of ==.
But it’s better and faster to use the ValuesBelow-function and the index operator.

Example:

Dim B = A
B[ValuesBelowLevel(A, 0, EVENT_INDEX)] = 0

hello, thank you for your reply!

when I use the valusebelow func, it replies:

index assignment to signals, signal serials.. are not allowed. assign the components seperately.

So do you have any further recommendation?

Thank you!

You have to assign the components seperately:

Dim B = A.Y
