Hi, Jason - 

Add these to your script: 

fmt='%02.0f'

cc=math_format(fmt,count)

'printim GFS-'cc'.png x1280 y960'

Hello,

Thank you all for your help.  I finally got it working.  I had the cases
wrong on a couple of the instances of 'count' .  Once I made them all the
same, it worked.

Here is another quick question, when I save the image, I use the following
format:

'printim GFS-'count'.png x1280 y960'

This saves an image with the file name: GFS-1.png

What do I need to do to get it to save with a double digit count as follows:
GFS-01.png

Thanks again for your assistance.

Jason

Hi 

Could you send me the section of the script just the loop start and finish
ie/

While ...
And 

Endwhile

Howard :)

Hello,

I tried that, and now I get an error that says "Set error, missing or
invalid arguments for T option, then is starts looping the first timestep.

Hi
After the while
'Set t 'count

....
Then the next time around the time step will increase ( count = count +1)
ie/ one time step advanced)

Should work then

Cheers Howard

Hi,

I almost have this working, but it does not advance through the timesteps.
It loads the first timestep, saves the image, then clears the screen, and
then loads the first timestep again, saves it, and so on.

Below is the script I set up to test this, so perhaps you can see where I
went wrong.  Thanks!

'set datawarn off'
'sdfopen
http://nomads.ncep.noaa.gov:80/dods/gfs_0p25/gfs20150209/gfs_0p25_12z'

Count = 1
while (count > 80)

'set t '1

'set lat 35 50'
'set lon -95 -65'
'set mproj scaled'
'set display color white'
'set map 1'
'set mpdset hires'
'set mpdraw on'
'set timelab off'
'set grid off'
'set font 0'
'set strsiz .1'

 'q time'
   timestr=subwrd(result, 3)
   weekday1=subwrd(result,6)
   day=substr(result, 11, 9)
   hr=substr(result, 8, 2)
  'draw string 9.1 0.2 'day' 'hr z
  'draw string 8.7 0.2 'weekday1

'set csmooth on'
'set cterp on'
'set gxout contour'
'set clopts -1 -1 0.06'
'set cmin 900'
'set cmax 1100'
'color 900 1100 2 -gxout contour -kind

'set cthick 2'
'd smth9(prmslmsl/100)'

'printim test'day'-'hr'z.png x1280 y960'

Count = Count + 1
'c'
endwhile

Print many variables for a time series (step through time series)

Count = 1
While (Count> 120                             final time step

'set t 'count                                          ie/ first time step

'set stuff lat lon maps etc

'd apcpsfc'                                           display variable
'd t2m'                                                 display another
variable
'd mslp'                                                            etc

Print image
'gxprint image_'Count .png x1200 y800'

Count = Count + 1                                          next time step
'c'
clear display
Endwhile                                                         loops
between While and
endwhile to print individual time steps          

kind regards
