[gradsusr] Making a Nested While Loop

[Muhammad Rahiz]

Saiguran,

The following script does as you require.

'sdfopen ifile.nc'

mtot = 4
m = 1
while ( m < mtot +1 )

* labels for title
s0 = ''DJF' 'MAM' 'JJA' 'SON''
s1 = subwrd(s0,m)

* dimensions for 2x2 plot
x1 = 11/2
x2 = x1 + x1
oo = 0.00
y1 = 8.5/2
y2 = y1 + y1

p1 = ''oo' 'x1' 'oo' 'x1''
p2 = ''x1' 'x2' 'x1' 'x2''
p3 = ''y1' 'y1' 'oo' 'oo''
p4 = ''y2' 'y2' 'y1' 'y1''

a1 = subwrd(p1,m)
a2 = subwrd(p2,m)
a3 = subwrd(p3,m)
a4 = subwrd(p4,m)

'set t 'm''
'set vpage 'a1' 'a2' 'a3' 'a4''
'set lat -20 20'
'set lon 20 60'
'set grads off'
'set mpdset mres'
'set gxout shaded'
'set clevs 288 290 292 294 296 298 300 304 306 308 310'

'd tmax'
'd u10;v10'
'draw title 's1''
'run cbarn'

m = m +1
endwhile

'printim image.png white'
'quit'
