[gradsusr] Dimensions that Grads can operate

[Jayakrishnan P.R]

Thanks. Eventhough the script after modification is working, the output
file is having some endian problem or the output figure is erroneous. The
modified script and ctl file is as follows.

*********************************************************************

'reinit'
'sdfopen G:/Sample_MT/samp/uwnd.2006.nc'
prompt 'key in filename'
pull fname
'set fwrite 'fname
yy=1
while(yy<=73)
xx=1
while(xx<=144)
'set x 'xx
'set y 'yy
tm=1
while(tm<=7)
  'set t 'tm
prl=1
while(prl<=8)
'set t 'tm
'set z 'prl
'set gxout fwrite'
'd uwnd'
prl=prl+1
         endwhile
       tm=tm+1
      endwhile
     xx=xx+1
   endwhile
 yy=yy+1
 endwhile
'disable fwrite'
