ForEach subscript

[jvh75021]

I am having trouble specifying the Current subscript in the ForEach step.

I have a local array of containers called FreqContainer where each container contains three numbers: LoFreq, MidFreq, and HiFreq.

On the ForEach Loop tab Array to Iterate Over is : Locals.FreqContainer, Current Element and Current Offset are blank. The Current Subscript  is a string, Locals.Iteration.

In a step in the foreach loop I try to access one of the elements using:

 Locals.CurrentFreqMHz = Locals.FreqContainer[Locals.Iteration].MidFreq

The subscript causes a problem, it appears to be '[''[0]'']'.

Can't find much useful documentation or examples on ForEach.

thanks, jvh

You probably need to do "[\"[0]\"]"

Perhaps my post was unclear, In the expression "Locals.CurrentFreqMHz = Locals.FreqContainer[Locals.Iteration].MidFreq", Locals.Iteration is being interpreted as '[''[0]'']'

Assuming you have a single dimensional zero-based array, you should use Current Offset, not Current Subscript.

The subscript is a string so that it can return a multidimensional subscript in a single value. To use it in an expression, you would need to call Evaluate such as:

Evaluate("Locals.MyArray" + Locals.Subscript) = 10

Thanks James.

I have been searching for documentation or an example that delineates the difference between subscript and offset. I think  there could be a little more information on ForEach and examples that use "offsets" and subscripts. Being a text coder, subscript seemed logical to me.

Much obliged.
