title: iMacros concatenating strings from datasource
body: <p>In the below iMacros how can I set a variable value and then concatenate it?</p>
  
  <pre><code>    VERSION BUILD=8530828 RECORDER=FX
      TAB T=1
      SET !ERRORIGNORE YES
      SET !DATASOURCE allsource.CSV
      SET !TIMEOUT 1
      SET !VAR! = My&lt;SP&gt;Content&lt;SP&gt;Here.
      TAG POS=1 TYPE=TEXTAREA FORM=ID:pst-main ATTR=ID:description CONTENT={{!COL1}}
  </code></pre>
  
  <p>How can the <strong>SET !VAR1 = MyContentHere.</strong> work? Please correct my syntax.</p>
  
  <p>And, how can I concatenate COL1 and VAR1 the below way didn't work</p>
  
  <p><code>TAG POS=1 TYPE=TEXTAREA FORM=ID:pst-main ATTR=ID:description CONTENT={{!COL1}} !VAR1</code></p>
  
  <p>Please correct my syntax, thanks</p>

  <p>Also, I am able to set Loop start as <code>SET !LOOP 2</code> how can I set LOOP end without manually setting Loop Number and hit <code>play loop</code> button? </p>
