Re: interpreting ARGV[]

[Miriam English]

And of course I realise a relatively simple solution straight after I
send the email. Here is a bit of example code:

        c["black"] = 1
        color = ARGV[1]
        print c[color]

Of course this means I'll have to reformat the assignments in the
library file's function so it defines the associative array's values
instead of simple values, but I can live with that.

Am I missing an even simple solution?

Cheers,

 - Miriam
