Summing over specific lines and replacing the lines with the sum
Hi friends,

This is sed & awk type question. It is slightly different from my previous question.

I have a text file which has numbers spread all over the file. I want to sum the series of numbers (but no more than 10 numbers in series) whenever i find it and produce an output file with the sum. For example

###start of input text file ####
Code:
abc
def
ghi
1
2
3
4
5
6
7
8
9
10
11
12
13
kjld
random
text
occupies
some
1000
3000
400
again
some
random
text
900
100
whatever
is here
900
11
what

#####end of input file #########

The output should be

##start of output file ####
Code:
abc
def
ghi
55
36
kjld
random
text
occupies
some
4400
again
some
random
text
1000
whatever
is here
911
what

########### end of output file #################

So the output file is the same as the input file, except the series of numbers (where series consists of ten or less consecutive numbers) is replace by its sum.

I hope it makes sense. If not, please let me know any questions.

Kind Regards,

NAME

       slarnv.f -

SYNOPSIS

   Functions/Subroutines
       subroutine slarnv (IDIST, ISEED, N, X)
	   SLARNV returns a vector of random numbers from a uniform or normal distribution.

Function/Subroutine Documentation
   subroutine slarnv (integerIDIST, integer, dimension( 4 )ISEED, integerN, real, dimension( * )X)
       SLARNV returns a vector of random numbers from a uniform or normal distribution.

       Purpose:

	    SLARNV returns a vector of n random real numbers from a uniform or
	    normal distribution.

       Parameters:
	   IDIST

		     IDIST is INTEGER
		     Specifies the distribution of the random numbers:
		     = 1:  uniform (0,1)
		     = 2:  uniform (-1,1)
		     = 3:  normal (0,1)

		     elements must be between 0 and 4095, and ISEED(4) must be
		     odd.
		     On exit, the seed is updated.

	   N

		     N is INTEGER
		     The number of random numbers to be generated.

	     128 using vectorisable code. The Box-Muller method is used to
	     transform numbers from a uniform to a normal distribution.
