<DIV>Hi ncl-users,</DIV>
<DIV> </DIV>
<DIV>I have encounted an error when reading a variable from an NC file.</DIV>
<DIV>the code is listed below:</DIV>
<DIV>;************************************************</DIV>
<DIV>load "$NCARG_ROOT/lib/ncarg/nclscripts/csm/gsn_code.ncl"</DIV>
<DIV>;************************************************</DIV>
<DIV>begin</DIV>
<DIV> inp0 = addfile("/public/home/chenf/AHWRF/TEST/WPSwks.T02/<A

<DIV
style="FONT-WEIGHT: bold"> lon2d = inp0->XLONG_M (Time|0, south_north|:, west_east|:)</DIV>
<DIV> printVarSummary(lon2d)</DIV>
<DIV>;************************************************</DIV>
<DIV>end</DIV>
<DIV> </DIV>
<DIV>the error message is:</DIV>

<DIV>Segmentation fault (core dumped)</DIV>
<DIV> </DIV>
<DIV>The strange thing is when i'm reading the variable without any dimention name cited, the error disappeared.</DIV>
<DIV>The code changes into :</DIV>

<DIV> </DIV>
<DIV>I don't understand why. It is very appreciate if anybody can tell
me the reason.</DIV>
<DIV>Thanks.</DIV>
