I don't know if I have tried this placement yet so I'll give it a whirl. Unless I am going crazy though, I don't see the geopoten. lines, despite the fact ccolor is at 0, which should be black. If I can't see them, I assume it is making them white, and I don't
know why.<br>

Okay, I put your script to work on a different computer system and got the results you're looking for (I think, see attached image). Here's the code that got those results:<br>
<br>
'open narr-a_221_19981218_0000_000.ctl'<br>
hgt = 850<br>
'set lev 'hgt<br>
'set lat 34 46'<br>
'set lon -114 -97'<br>
'set mpdset hires'<br>
'set display color white'<br>
'clear'<br>
tt = 1<br>
while (tt <= 8)<br>
'set t 'tt<br>
'set cint 10'<br>
'set ccolor 0'<br>
'd HGTprs'<br>
'set clab %.0f`3.`1C'<br>
'set cint 2'<br>
'set cstyle 2'<br>
'set ccolor 2'<br>
'd (TMPprs - 273)'<br>
'set gxout barb'<br>
'd skip(UGRDprs,3,3);VGRDprs;mag(UGRDprs,VGRDprs)'<br>
'printim example_'tt'_'hgt'.png x800 y600'<br>
'clear'<br>
tt = tt + 1<br>
endwhile<br>
<br>
You'll notice the only things I changed (other than the path to the files) is where I put some of the setup commands, and that I removed the "set background" command. You don't need to use both "set background" and "set display" to get what you want. In fact,
I think those two commands sort of canceled each other out. I would suggest always going with the "set display color white" ; "clear" sequence. Changing either the background or display color messes with the color that represents the "foreground" and "background".
When you did "set background 1", you told Grads to set the color index 1 to black and 0 to white instead of the other way around, which is the default behavior. I don't know if it matters to get much deeper than that, but just use the suggestion I provided
and you'll be fine.<br>

I reduced the iterations to one, and I still cannot get these commands in the script to do the same thing when typing them one by one on the command line with a refresh load of grads. Has anyone had this happen before? Could someone run my script and tell me
if you still only get a black background, despite the command?<br>

Absolutely nothing will work. Even if I use white in printim the image is STILL black. This is such a huge waste of time at this point. Should it be so hard to get a script to work right?<br>

Try moving your 'clear' command to the line after you 'set display color white', e.g.,<br>
<br>
'set background 1'<br>
'set display color white'<br>
'clear'<br>
<br>
That might work.<br>
