<div> </div>
</div>
<div>You can save variables to netcdf with dynamic names:
<div class=""><font face="InputMono-Regular" class="">ncdf->$tostring("var"+i)$ = some_variable</font></div>
<div class=""><br class="">
</div>
<div class="">But you can’t have dynamic variable names in the script. The closet would be attaching attributes with dynamic names. e.g.</div>
<div class=""><br class="">
</div>
<div class=""><font face="InputMono-Regular" class="">x = ispan(0,5,1)</font></div>
<div class="">
<div class=""><font face="InputMono-Regular" class="">holder = True</font></div>
<div class=""><font face="InputMono-Regular" class="">do i=0,5</font></div>
<div class=""><font face="InputMono-Regular" class=""> holder@$tostring("var"+i)$ = x(i)</font></div>
<div class=""><font face="InputMono-Regular" class="">end do</font></div>
</div>
<div class=""><font face="InputMono-Regular" class=""><br class="">
</font></div>
<div class=""><font face="InputMono-Regular" class="">
<div class="">> Variable: holder</div>

<div class="">> var3 :<span class="Apple-tab-span" style="white-space:pre"> </span>

<div class="">> var2 :<span class="Apple-tab-span" style="white-space:pre"> </span>

<div class="">This is could get messy pretty quickly though. </div>
<div class=""><br class="">
</div>
<div class="">Google "ncl-talk dynamic variable names” and you’ll find a bunch of old threads asking similar questions. </div>
<div class="">It usually boils down to why would you want this? For output there is the method above, otherwise save variables in an array, the names are somewhat irrelevant. Also I imagine trying to debug a script with unknown variable names would be a nightmare. </div>
