Most efficient way to compare 100s of variables

Hey,

I have a general idea how to do this but i’m not sure its the most efficient. I’m hoping someone can share something more efficient.

Scenario:

  1. Robot collects data using get text activities for about 100 different items
  2. Robot then uses the information from the get text activities and calculates new values for these 100 different items
  3. Robot then uses type into activities and overrides all these 100 different items from step 1

What I’m looking to compare:
a) Compare each of the 100 items in 1) with 3) and note which ones are different
b) Compare each of the 100 items in 2) with 3) and note which ones are different

Solution I was thinking:
Build a data table that aligns each item from 1), 2), and 3) and then use a for each on the table.

Issue with my solution:
I will need to add in 100 add data row items with the 3 variables each in an array

Does anyone have a more efficient way to do this?

If there is not, is there a way to print out a list of all my variable names? At least that way I can populate the add data row activities a little easier.
