title: Testing for Characters over a String
body: <p>aSimple question i got, what's the easiest way to check if my String includes any alphabetic characters?? rather than streaming over it. I tried "isAlphaNumeric" gives me an error.</p>
  
  <pre><code> |a|
   a:= '1625.46brd'.
   "check if a includes alphabets "
  </code></pre>
