<p style="margin-top:0; margin-bottom:0">Hi All,<br>
I have a variable with a list of values (they're correlations) in it. I'm creating a new variable with an equally sized list of synthetic values spanning the "range" of values in the original variable, like so:<br>
<br>
<span>randomcorrs = random_uniform(min(<wbr>pastregimecorrs),max(<wbr>pastregimecorrs),num(<wbr>pastregimecorrs))<br>

a printVarSummary on "<span style="font-family:Calibri,Helvetica,sans-serif,Helvetica,EmojiFont,"Apple Color Emoji","Segoe UI Emoji",NotoColorEmoji,"Segoe UI Symbol","Android Emoji",EmojiSymbols; font-size:16px">pastregimecorrs" yields:<br>

Although this always seems to work as expected, I get the following warning:<br>
<br>
<p style="margin:0px; font-style:normal; font-variant:normal; font-weight:normal; font-size:11px; line-height:normal; font-family:Menlo; color:rgb(215,201,167); background-color:rgb(142,53,40)">

<p></p>
<p style="margin-top:0; margin-bottom:0"><br>
</p>
<p style="margin-top:0; margin-bottom:0">This isn't the biggest deal, other than I loop through this 1000x20x11 times, so it creates a lot of warning text which is making it difficult to debug other portions of my code. "randomcorrs" has not been previously
defined. </p>
<p style="margin-top:0; margin-bottom:0"><br>
</p>
<p style="margin-top:0; margin-bottom:0">My question is, am I doing something wrong here? It's not clear to me that I'm doing anything other than what <span style="font-size:12pt">random_uniform (or min, max, or num) expect. I've spent an inordinate amount
of time trying to figure this out, so either I'm missing something exceptionally obvious (very possible) or this is a gratuitous warning. I'm using NCL 6.3.</span></p>
