% This demonstrates that a local variable defined in one chunk of Ruby code
% can be picked up and used in a later chunk.

{: x = 99999 :}

{: 25.times do :}
  \noindent Did you know that
  {: new_x = Math.sqrt(x) :}
  $\sqrt{{:= "%0.10f" % x :}} \approx {:= "%0.10f" % new_x :}$?\par
  {: x = new_x :}
{: end :}

Maybe if you're Rain Man.

% The following shows that local variables don't persist across a 'require'
% statement.  Local variables defined in required file disappear on return.
% Use a global variable $var to communicate between files.

{: require './testbind' :}

The `required' file set x to 1957, but it still reads {:= x :} in the \LaTeX\
doc.  However, the global variable \$x set to 1957 in the required file is {:=
  $x :} %$
in the \LaTeX\ file.
