<br>I suspect you are entering GrADS scripting syntax at the "ga->" command line; this is a very common mistake we always make when we are starting with grads. Review the User's Guide, there is a lot of useful information there.<br>

<br>for submitting questions to gradsusr. These are important so that we know exactly which version of the software you are running. For example, "grads OPeNDAP" does not give us nearly enough information to know what you are running.<br>

Additionally, I looked at <a href="http://nomads.ncdc.noaa.gov/dods/NCEP_NARR_DAILY/197901/197901/narr-b_221_197901dd_hh00_000.info" target="_blank"><font color="#0000ff">http://nomads.ncdc.noaa.gov/dods/NCEP_NARR_DAILY/197901/197901/narr-b_221_197901dd_hh00_000.info </font></a> and saw some asterisks. When I put down d weasd3hr, I got the following error message:gancgrid error: unable to allocate memory for grtmp grid storage </p>
<p style="margin: 0px;"> grid size = xlen * ylen * zlen * tlen * elen = 28 * 28 * -999 * 1 * 1 </p><p style="margin: 0px;">Data Request Error: Error for variable 'weasd3hr' </p><p style="margin: 0px;"> Error ocurred at column 1 </p>
<p style="margin: 0px;">DISPLAY error: Invalid expression </p><p style="margin: 0px;"> Expression = weasd3hr. </p><p style="margin: 0px;">Why was that?</p></font></blockquote><div><br>The error message "<font><font face="Default Sans Serif,Verdana,Arial,Helvetica,sans-serif" size="2">unable to allocate memory" means just that: your computer is running low on memory. Close some applications or add some more RAM. There is also some chance that there is a bug in GrADS that is causing it to tun out of memory. We would need more information in order to diagnose that.</font></font><br>

How am I suppose to know?<br><br>As a general rule, I think it is very important for us to share our knowledge with new users but there are some basic "Netiquete" rules that we all need to be attentive to, e.g.,<br>
