How do you make an array to manipulate?

Question

I mean I want to do metrics math and stuff

Answer 1

If you mean make an array, it's quite easy, bud.

Simply write:

VarName = {arrayItem1, arrayItem2, arrayItem3}

Obviously change VarName with the name you want your array to have and change arrayItems to whatever you want. Arrays aren't limited to 3 items btw!

Answer 2

you need perl array instead.
