tab
==============================================

Purpose
----------------

Tabs the cursor to a specified text column.

Format
----------------
.. function:: tab(col) 

    :param col: the column position to tab to. Can be in the following format:
    :type col: scalar

Remarks
-------

Can be specified multiple times in a `print` statement:

::

    print expr1 expr2 tab(col1) expr3 tab(col2) expr4 ...


*col* specifies an absolute column position. If *col* is not an integer, it
will be truncated.

`tab` can be called alone or embedded in a `print` statement. You cannot
embed it within a parenthesized expression in a `print` statement, though.

For example:

::

   print (tab(20) c + d * e);

will not give the results you expect. If you have to use parenthesized
expressions, write it like this instead:

::

   print tab(20) (c + d * e);

Examples
--------

::

    // Use tab to align output in columns
    print "Name" tab(20) "Score" tab(35) "Grade";
    print "Alice" tab(20) 95 tab(35) "A";
    print "Bob" tab(20) 82 tab(35) "B";
