Multiple Numeric Limit Test - Unknown number of steps

Hello,

I would like to know how to "pre-expression" the number of steps in order to dynamically allocate the number of 

Results.Measurement

Numeric Array

Data Source Array.

In my project I extract all the results from a csv file, including the number of steps or sequences, using NI - CVI. And it is this number of sequences that I can not preprogram in TestStand main sequence prior to calling CVI, ie I can only set during execution, after returning from the CVI with data.

Note in a regular array, I know how to dynamically set the dimensions, for eg:

In the pre-expression I write:

SetNumElements(Local.Array,Locals.testSize)

That is to say, an "empty" array in Locals, called Locals.Array, initially has NO dimensions, with the "empty" box ticked.

Then when I retrieve the size: "testSize" , say from a CVI call, the array will now be prerset to one dimensional Array of testSize from the pre-conditions,

However, this ploy is not accepted for:

pre-expression in Multiple Numeric Limit Test.

I tried writing a pre-expression:

Step.ExpectedNumMeas = Locals.testSize,

SetNumElements(Step.Results.Measurement,Locals.testSize),

SetNumElements(Step.NumericArray,Locals.testSize),

SetNumElements(Step.DataSourceArray,Locals.testSize)

This yielded nothing.

Any ideas?

Thanks.
