[gradsusr] Loop help

[Muhammad Yunus Ahmad Mazuki]

How about this? Replace the integer 1 with a script variable year, and
integer 2 with scrip variable tvalue.

year=1
tvalue=673
*start loop
while(loop<=672)
*your loops, example
'define y'year'=pdsi.1(t='tvalue')'
year=year+1
tvalue=tvalue+1
endwhile

Notice that y1= becomes y'year'= . If you want to put the variable at then
end, say you want to display t1 until t672, you need to leave out the '
mark at the end, example

'display t'year

Its the same if you're using something in the front.

variable'mean=something(something)'

The script variable are in string, so you can do lots of things with it,
including looping variables being plotted, automated plots title
corresponding to time of your choosing and others. So in one loop, you can
calculate, plot (with correspoding title, matching contours or shades) and
save them in pictures or binaries form.

For more information, please refer to GrADS scripting.
