Hello Joe,<br><br>Your time query is introducing a space into the "day" variable. PRINTIM doesn't like spaces in the filename string. Try this instead:<br><span style="font-family: courier new,monospace;">day=substr(result, 11, 9)</span><br>
<br>It should work with above change.<br><br>Stephen McMillan<br><div class="gmail_quote">On Sat, Sep 3, 2011 at 4:53 PM, Joe Moore <span dir="ltr"><<a href="mailto:joe@wxjoe.com">joe@wxjoe.com</a>></span> wrote:<br>

<br>Problem: When using a variable in the filename to save the output, I'm getting an error. <br><br>Here's the relevant code:<br><br><span style="font-family: comic sans ms,sans-serif;">'printim out/RTMA_TMP_'day'_'hr'.png'</span><br style="font-family: comic sans ms,sans-serif;">
<br>where I am defining the variable day and hour using the following:<br><span style="font-family: courier new,monospace;">'q time'</span><br style="font-family: courier new,monospace;"><span style="font-family: courier new,monospace;">hr=substr(result, 8, 2)</span><br style="font-family: courier new,monospace;">
<span style="font-family: courier new,monospace;">day=substr(result, 11, 10)</span><br><br>The result of which, when I print as a string or in the title, comes out to be 23 for the hour and 16AUG2011.<br><br>Expect result: I should have a file output called RTMA_TMP_16AUG2011_23.png<br>
<br>What actually is happening: The file output is just called RTMA_TMP_23AUG2011 (that's it- no .png) and when I run I get the following error: PRINTIM error: Invalid option; ignored<br><br>I've been able to sometimes get this to work, like if I put a few characters (not including an underscore or period) in the output filename - but I can't figure it out. I'd like to use either underscores, dashes or periods to separate the variables in the output file name, and I've seen it done in example scripts I've found on the web.<br>
<br>Configuration: I am running OpenGrADS 2.0.a9.oga.1 on Ubuntu 11.04. The data is coming from the RTMA grib2 from the NOAA NOMADS server. Here is my full grads config info:<br><span style="font-family: courier new,monospace;">ga-> q config</span><br style="font-family: courier new,monospace;">
