Manipulating values inside a List?

[R2D2]

hi!

 

I couldn't find a better area for this topic.

But I have a variable $RowList which is defined to contain numerical values in List(FieldA; FieldB; FieldC; FieldD,..., FieldK). That is inside a Loop ($i as a counter). I would like to do some testing for each of them in turn (like: If (GetValue($RowList; $i) > x) then set $RowList value $i to something else). And then return the modified whole list back to a variable.

 

Is that possible?

To replace a value at index position in listOfValues, you can use:

LeftValues ( listOfValues ; index - 1 )
&
replacementValue & ¶
&
RightValues (  listOfValues ; ValueCount ( listOfValues ) - index )

Note that the result will have a trailing ¶.

A good custom function to add to your file.

That function performs a task that is fundamentally different from the one required here (at least the way I understood it).

Yes, sorry read too quickly.

Thank you comment and bcooney! The way, comment showed, is what I need. But this custom function is also very useful for me.👍

Note also that if you're looping over a list of values, you can add each processed value to a new list in another variable, say:

Set Variable [ $result ; List ( $result;  If ( GetValue ( $RowList ; $i ) > $x ; "a" ; "b" ) ) ]
