Does anybody know can you change the output 'nil' to a different string
using literal notation? Besides constructor?
Hash_Name = Hash.new(Anything other than nil!)
Hash_name = {
key = value
}(Anything other than nil!)
New at this,
umm as long as a variable does not have special characters or a space in
it, as far as I am aware I thought variables are case sensitive, but
should work. The example above I see a variable needs to be ALL_CAPS or
all_lowercase, you cannot HaVe_bOtH. Is that correct?

In ruby, any variable whose name starts with a capital letter becomes a
constant.

Which implies there are actually constants in Ruby.

Jordan Bedwell is correct. Ruby's constants are /meant/ to be not changed, but
you can define a constant and change its value later. Ruby will produce a
warning 'already initialized constant'
Also note that your constant's internal representation can be changed without
triggering the warning.
I didn't know that, thank you!
