If you mean first letter :

name[0] #shows code
name[0].chr #shows letter

Try String#[] or String#slice, but since they return a number (the code
of the
first character) if you only specify an index, you’ll need to pass the
index
and a length of 1, like this:

“test string”[0,1]
=> “t”

For more information, see the documentation for the String#slice method
(ri
String#slice).

“ASDASDAS”[0] -> 65

“ASDASDAS”[0].chr -> “A”

Please add http://www.ruby-doc.org/core/ to your Favorites, look at
Class “String” and you will find everything you need.
