[gradsusr] image from each timestep

[Stephen McMillan]

No problem, Jason.  To handle multiple parameters, it depends on what you
want the end result to be.  For example, if you want to overlay contour
lines on a shaded contour plot, change the output accordingly ('set gxout
contour') and display your variable within the same timestep setting.  Add
an additional plot (e.g., wind barbs) if desired.  However, if you want to
write a separate image for each parameter at the same timestep, display
your variable and do your 'printim...'  for each parameter in succession,
before the end of the while loop.  Most GrADS functions have an example or
two in the GrADS Documentation Index (
http://www.iges.org/grads/gadoc/gadocindex.html).  Following are simplified
samples of the two ways.
Stephen Mc

while...
  'c'
  'd [var1]'
  'd [var2]'
  'd [var3]'
  'printim....'
  ts=ts+1
endwhile

OR

while...
  'c'
  'd [var1]'
  'printim...'
  'c'
  'd [var2]'
  'printim...'
  'c'
  'd [var3]'
  'printim...'
  ts=ts+1
endwhile
