Clarify more on the requirement
Thank you all for responding me - however the requirement was different .

let me clarify it in more simpler -

Input file -
Code:
col_1,col_2,col_3,col_4,col_5,col_6,col_7,col_8,col_9,col_10,col_11
3010,21,1923D ,0,5,10,15,20,25,1,200807
3010,21,192BI ,0,60,65,70,75,80,1,200807
3011,22,192xx ,0,20,30,40,50,60,2,200903
3011,22,192xx ,0,25,30,40,50,60,2,200903
3011,22,192xx ,0,50,55,60,65,70,3,200903
3011,22,192xx ,0,25,30,40,50,60,3,200903

Column 10 contain category 1 , 2, 3
Out put would be-- At the end of each category it would print the
sum of column 5,6,7,8,9 and rest are just blank

Example :
Code:
col_1,col_2,col_3,col_4,col_5,col_6,col_7,col_8,col_9,col_10,col_11
3010,21,1923D ,0,5,10,15,20,25,1,200807
3010,21,192BI ,0,60,65,70,75,80,1,200807
,,,,65,75,85,95,105,,,  
col_1,col_2,col_3,col_4,col_5,col_6,col_7,col_8,col_9,col_10,col_11
3011,22,192xx ,0,20,30,40,50,60,2,200903
3011,22,192xx ,0,25,30,40,50,60,2,200903
,,,,45,60,80,100,120,,,
col_1,col_2,col_3,col_4,col_5,col_6,col_7,col_8,col_9,col_10,col_11
3011,22,192xx ,0,50,55,60,65,70,3,200903
3011,22,192xx ,0,25,30,40,50,60,3,200903
,,,,75,85,100,115,130,,

After end of each category it is printing the sum of col4 ,sum of col 5 ,sum of 6,sum of col7,sum of col 8,sum of col9 and then it start the header again then then same process for each category

Hope this helps to formulate an solution

NAME

       sum - calculate a sum(1) compatible checksum

SYNOPSIS

       package require Tcl 8.2

       package require sum ?1.0?

       ::crc::sum ?-format format? message

       ::crc::sum ?-format format? -filename file

DESCRIPTION

       This  package  provides	a Tcl-only implementation of the sum(1) command which calculates a 16 bit checksum value from the input data.  The
       BSD sum algorithm is used by default but the SysV algorithm is also available.

COMMANDS

       ::crc::sum ?-format format? message

       ::crc::sum ?-format format? -filename file
	      The command takes string data or a file name and returns a checksum value calculated using the sum(1) algorithm. The result is  for-
	      matted using the format(n) specifier provided or as an unsigned integer (%u) by default.

OPTIONS

       -filename name
	      Return a checksum for the file contents instead of for parameter data.

       -format string
	      Return the checksum using an alternative format template.

EXAMPLES

       % crc::sum "Hello, World!"
       37287

       % crc::sum -format 0x%X "Hello, World!"
       0x91A7

       % crc::sum -file sum.tcl
       13392
