<div dir="ltr"><h2><font><span style="font-weight:normal">If you have NCL Version 6.1.1 (February 4, 2013) you could replace the <br></span></font></h2><p><br></p><p> time_index(..) = ...<br></p><p> :</p><p> delete(time_index)</p><p><br></p><p>==============</p><p>with the reassignment operator</p><p> time_index(..) := ...</p><p><br></p><p>
<b>New reassignment operator</b></p><p>
There's a new operator, ":=", that allows you to reassign variables
without having to delete them first.<br>
For example:
</p><p>
</p><pre> x = fspan(-10.5,20.8,0.1) ; array of floats
; x = "This is a string" ; this won't work
x <b>:=</b> "This is a string" ; single string
</pre>
<p>
This operator works for attributes as well, but not for coordinate arrays.
</p><p> <br></p>
