It would be a relatively simple function to write if you intend to use it frequently and likely worth it compared to the wasted time of reading in unnecessary data from the file.</span></div><div><span style="font-size:12.8000001907349px"><br></span></div><div><span style="font-size:12.8000001907349px"><br></span></div><div><span style="font-size:12.8000001907349px">Kyle</span></div></div><div class="gmail_extra"><br clear="all"><div><div class="gmail_signature"><div dir="ltr">----------------------------------------<div>Kyle S.

the problem is being at to specify a range of colons, e.g.<br>
<br>
:,:,:<br>
<br>
:,:<br>
<br>
:<br>
<br>
without having to use if else if statements…some languages have a function for this, it may not be easy to implement in NCL.<br>
<br>
It would be a way of making certain code more compact and general.<br>
