ELI Output
----------

Direct variable output
~~~~~~~~~~~~~~~~~~~~~~

A variable or a constant can be displayed directly in both workspace and scripts.

.. code-block:: none

        x <- 1 2 3
        x
    1 2 3
        'abc'
    abc

`[]` and `[)` functions
~~~~~~~~~~~~~~~~~~~~~~~

- `[]` is used to display the content of a value and print a return at the end.
- `[)` is the same as the function `[]` except that there is no a new line at the end.

.. code-block:: none

        []<-x
    1 2 3


~~~~~~~~~

.. note::

    The direct variable output can't display all values if screen limititation is reached.  Therefore, the function `[]` allows display all rows and columns, especially when you have a large table.

.. Todo:
.. 1. what's screen limitation
.. 2. string formating
