For loop / test for equality

[A0BL7N]

Hello,

I have a sample of 640 data series, which are subdivided into 320 pairs. I now need to run tests for equality of the means and medians of each of these pairs.
The manual way to do this for the first pair is:

Select Series1 and Series2 --> Open as group --> View --> Test for equality --> Median

The code to do this for the first pair is:

group a Series1 Series2
show a.testbtw(median)

In order to be more time efficient, I now would like to create a program which contains a for loop in order to perform the different tests of the 320 pairs automatically.

Could anybody help me on this? Many thanks in advance.

What is the naming convention between the 640 series? Is the a way to logically connect the pairs?
