Also, the exact text of the error message you're getting is critically important. The phrase "unknown operator" does not appear anywhere in the GrADS code. That being said, your problem is likely caused by the fact that you're not using a version of GrADS that supports the E dimension.</div><div>--Jennifer</div><div><br></div><div><div><br><div><div>On Nov 29, 2010, at 11:39 AM, eric delaere wrote:</div><br class="Apple-interchange-newline"><blockquote type="cite"><div class="hmmessage" style="font-size: 10pt; font-family: Tahoma; ">hi<br><br>do somebody knows why my script returns the error 'unknown operator 'e 10'<br>In the docs, 'set e' is a legal operator??<br>thx<br><br>function main( args )<br>'reinit'<br><br>'sdfopen<span class="Apple-converted-space"> </span><a href="http://nomads.ncep.noaa.gov:9090/dods/gens/gens20101129/gep_all_06z'">http://nomads.ncep.noaa.gov:9090/dods/gens/gens20101129/gep_all_06z'</a><br><br>'set display color white'<br>'clear'<br>'set display color white'<br><br>say 'calculating pre-data ==> Ok!' <span class="Apple-converted-space"> </span><br><br>'set e 10'<br>'set lon 5'<br>'set lat 50'<br>'set lev 500'<br>'set t 0.5 65.5'<br><br>'set parea 1 9.7 2.5 6'<br>'set grads off'<br>'set tlsupp year'<br>'set cmark 0'<br>'set vrange 4950 5600'<br>'set ylint 100'<br>'d hgtprs'<br><br>'printim c:\model\upload\test\test-'timer'.png'<span class="Apple-converted-space"> </span>_______________________________________________<br>gradsusr mailing list<br><a href="mailto:gradsusr@gradsusr.org">gradsusr@gradsusr.org</a><br><a href="http://gradsusr.org/mailman/listinfo/gradsusr">http://gradsusr.org/mailman/listinfo/gradsusr</a><br></div></blockquote></div><br><div apple-content-edited="true"> <span class="Apple-style-span" style="border-collapse: separate; border-spacing: 0px 0px; color: rgb(0, 0, 0); font-family: Helvetica; font-size: 12px; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: normal; text-align: auto; -khtml-text-decorations-in-effect: none; text-indent: 0px; -apple-text-size-adjust: auto; text-transform: none; orphans: 2; white-space: normal; widows: 2; word-spacing: 0px; "><div style="word-wrap: break-word; -khtml-nbsp-mode: space; -khtml-line-break: after-white-space; "><span class="Apple-style-span" style="border-collapse: separate; border-spacing: 0px 0px; color: rgb(0, 0, 0); font-family: Helvetica; font-size: 12px; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: normal; text-align: auto; -khtml-text-decorations-in-effect: none; text-indent: 0px; -apple-text-size-adjust: auto; text-transform: none; orphans: 2; white-space: normal; widows: 2; word-spacing: 0px; "><span class="Apple-style-span" style="border-collapse: separate; border-spacing: 0px 0px; color: rgb(0, 0, 0); font-family: Helvetica; font-size: 12px; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: normal; text-align: auto; -khtml-text-decorations-in-effect: none; text-indent: 0px; -apple-text-size-adjust: auto; text-transform: none; orphans: 2; white-space: normal; widows: 2; word-spacing: 0px; "><div>--</div><div>Jennifer M.
