Custom Tasks: Checking whether inputtext has a value

Hi,

 

I'm finding my way around defining custom tasks within SAS Studio (v3.5) and I was wondering if there's a way of checking whether the Velocity variable for the INPUTTEXT option element exists or not. So I only want this Velocity variable to appear in the SAS code if the INPUTTEXT has been completed by the user.

After a bit of research and some trial and error I found that the following VTL works:

 

    <CodeTemplate>
    <![CDATA[
#if ($textExample.empty=="false") $textExample #else NULL TEXT #end
    ]]>
  </CodeTemplate>

 

So this piece of code checks whether the Input Text variable is empty/missing ("true") or non-missing ("false"). I wanted to use this for optional macro parameters that require text when creating a Tasks to create a standard macro wizard.
