Hi Bekele,
Examples of Inbuilt GrADS scripts can be found in GrADS manual. For your 
purpose you may write the script given below

==============
'open SRF1998010100.ctl'
'set fwrite 98rf.dat'
'set gxout fwrite'
*//To Average tpr for Lon 88-92, Lat 10 20 for time 1 to 240
'd aave(ave(tpr,t=1,t=240), lon=88, lon=92, lat=10, lat=20)'
'disable fwrite'
'close 1'
return
==========
Note: It will prepare 98rf.dat file that contains precipitation values in 
digital format, 8 digits for each data value. Now you may convert this data 
values using FORTRAN code with your criteria of 10 mm/day etc. For numerical 
functions please see grads manual.
