Go to position in an array?

General
1

I'm trying to create an array 0-28 because an API call I'm making gives me no information on what algorithm it's returning except its numerical identifier [0-28]. So I want to make a global list with all the algorithms in text, since that's easier to understand than an array position.

Essentially I'm trying to do something like:

$gv(algorithm[wget(url, json, ".array[length]"-1)])$

Which would output: ExampleAlgorithm

You cannot create a list global out of a list right now BUT you can use split, so, lets say that your json output is something like "foo,bar,mike" then you can just use $tc(split, "myjson", ",", 1)$ to access the second value "bar"
