Array indices

ruby-talk

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"]

harp:~ > cat a.rb
   # gem install arrayfields
   require 'rubygems'
   require 'arrayfields'

   myarray = [1,2,3,4,5]
   myarray.fields = ['A','B','C','D','E']

   p myarray['A']
