Is there a way to set the indice on an array,
i.e.
Instead of:
myarray = [1,2,3,4,5]
myarray[1] =2
myarray[4]=5
myarray[A]=1
I know this can be done using hashes but was not sure with arrays

Check the docs for the Array class. I know there’s a method which
does this (several variations on it, actually), but I can’t remember
what it’s called.

Negate that last answer - I misunderstood. Sorry.
Anyway, array indices are always integers. As long as A references
or evaluates to an integer, no problem:
A = 3
myarray = []
myarray[A] = “foo”
=> [nil, nil, nil, “foo”]
