# When =. and =: are the same

You have seen how `=.` and `=:` are different when used in a verb definition.

When you execute sentences in the ijx window you are not executing them inside a verb so the `=.` and `=:` have the same effect. In the ijx window:

       a =. 123
       a
    123

       a =: 234
       a
    234

In the ijx window the `=.` and `=:` copulas are the same and it doesn't matter which you use to define a name as they both define the global name. The `=.` is easier to type and tends to be the one that is used. In a strict sense it would be better to explicitly use `=:` when defining a global name.
