Dear James,<br>Could you send me please the link to this email database. Surely it will save a lot of time to many of us.<br>Thank you.<br>Hernán.<br><br><div class="gmail_quote">2009/4/13 James T. Potemra <span dir="ltr"><<a href="mailto:jimp@hawaii.edu">jimp@hawaii.edu</a>></span><br>

are archived in a database, and this database becomes almost useless<br>
with subject lines such as "Please help", or "question", etc. I'm sure<br>
many mail filters, human and otherwise, delete these on receipt. Please<br>
try and use a subject line that is somewhat meaningful; this will save<br>
time in the future for those who search the archive. Thanks,<br>
<br>

To all:<br>
<br>
<br>
<br>
I have a couple of questions: when I use<br>
rc=write(Jan1979.ctl, dset Jan1979.dat), I get the following<br>
message: Syntax Error: Invalid Operand<br>
<br>
'write' not a variable or function name<br>
<br>
Error ocurred at column 1<br>
<br>
DEFINE error: Invalid expression.<br>
<br>
Why does that happen?<br>
<br>
<br>
How much of the User's Guide have you read?<br>
<br>
<a href="http://grads.iges.org/grads/gadoc/users.html" target="_blank">http://grads.iges.org/grads/gadoc/users.html</a><br>
<br>
I suspect you are entering GrADS scripting syntax at the "ga->"<br>
command line; this is a very common mistake we always make when we are<br>
starting with grads. Review the User's Guide, there is a lot of useful<br>
information there.<br>
<br>
<br>
I am running grads OPeNDAP<br>
<br>
<br>
There are some guidelines under<br>
<br>
<a href="http://grads.iges.org/grads/users.html" target="_blank">http://grads.iges.org/grads/users.html</a><br>
<br>
for submitting questions to gradsusr. These are important so that we<br>
know exactly which version of the software you are running. For<br>
example, "grads OPeNDAP" does not give us nearly enough information to<br>
know what you are running.<br>
<br>
<br>
<br>
Additionally, I looked at<br>
<a href="http://nomads.ncdc.noaa.gov/dods/NCEP_NARR_DAILY/197901/197901/narr-b_221_197901dd_hh00_000.info" target="_blank">http://nomads.ncdc.noaa.gov/dods/NCEP_NARR_DAILY/197901/197901/narr-b_221_197901dd_hh00_000.info</a><br>
<<a href="http://nomads.ncdc.noaa.gov/dods/NCEP_NARR_DAILY/197901/197901/narr-b_221_197901dd_hh00_000.info" target="_blank">http://nomads.ncdc.noaa.gov/dods/NCEP_NARR_DAILY/197901/197901/narr-b_221_197901dd_hh00_000.info</a>> and<br>
saw some asterisks. When I put down d weasd3hr, I got the<br>
following error message:gancgrid error: unable to allocate memory<br>
for grtmp grid storage<br>
<br>
grid size = xlen * ylen * zlen * tlen * elen = 28 * 28 * -999<br>
* 1 * 1<br>
<br>
Data Request Error: Error for variable 'weasd3hr'<br>
<br>
Error ocurred at column 1<br>
<br>
DISPLAY error: Invalid expression<br>
<br>
Expression = weasd3hr.<br>
<br>
Why was that?<br>
<br>
<br>
The error message "unable to allocate memory" means just that: your<br>
computer is running low on memory. Close some applications or add some<br>
more RAM. There is also some chance that there is a bug in GrADS that<br>
is causing it to tun out of memory. We would need more information in<br>
order to diagnose that.<br>
<br>
<br>
Finally, I have the CD.<br>
<br>
<br>
Hmm. CD? Which CD is that? How am I suppose to know?<br>
<br>
As a general rule, I think it is very important for us to share our<br>
knowledge with new users but there are some basic "Netiquete" rules<br>
that we all need to be attentive to, e.g.,<br>
<br>
<a href="http://www.livinginternet.com/i/ia_nq_basics.htm" target="_blank">http://www.livinginternet.com/i/ia_nq_basics.htm</a><br>
<br>
In particular, "research before you ask" and always review your<br>
message asking yourself: am I providing enough information for someone<br>
to be able to understand and ideally reproduce my problem?<br>
