I followed your procedure accurately;
Everything else worked except for the vpage options!
SET error: Missing or invalid arguments for VPAGE option
All the four images are overlaid on each other on the full page!

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'
