Does "untyped" mean the same as "dynamically typing"?
<p>According to <a href="http://tldp.org/LDP/abs/html/untyped.html" rel="nofollow">Advanced Bash-Scripting Guide</a>,</p>

<ol>
<li><p>bash variables are untyped:</p>

<blockquote>
  <p>Unlike many other programming languages, Bash does not segregate its variables by "type." Essentially, Bash variables are character
  strings, but, depending on context, Bash permits arithmetic
  operations and comparisons on variables. The determining factor is
  whether the value of a variable contains only digits.</p>
</blockquote>

<p>The link also gives examples.</p>

<p>Does "untyped" mean the same as the concept of "dynamically typing"
in programming languages?  If not, what are the relations and
differences between the two?</p></li>
<li><blockquote>
  <p>To lighten the burden of keeping track of variable types in a script, Bash does permit <a href="http://tldp.org/LDP/abs/html/declareref.html" rel="nofollow">declaring</a> variables.</p>
</blockquote>

<p>For example, declare a variable to be integer type, by <code>declare -i
myvariable</code>.  </p>

<p>Is this called "typed" variables? Does "typed" mean
the same as the concept of "statically typing"?</p></li>
