Hello Grads experts,<br><br>Is there any recommendation for the following situation.<br><br>After I define a variable VAR (assume daily data) for a period of <br>long time, can I selectively choose a shorter sub-period within this full<br>
period and set VAR to undef value, and still<br>use the full period of VAR values, with this newly set undefined<br>value for that sub period? I hope this is not confusing.<br><br>The problem I run into is, when I try to redefine VAR <br>
for the shorter period, full period VAR gets deleted, and a new VAR<br>is created only for the shorter period.<br><br>Thanks for any help/suggestions.<br><br>Muthu<br><pre cols="72"><font style="font-family:tahoma,sans-serif">------------------------------------------------------------------<br>
