Replace column by random number addition
Here is my problem:-

I have a file with pipe separated values.

Code:
CR|20121021|079|ABC|N|DLS|00038|DLS|04750|1330597704|634234|634|0

Now I want to replace field: 10 (highlighted) by adding a random number to field number: 11. But the random number has to be generated based on decimal places of field: 11

E.g: In the first record, the 11th field value is 634234, so we have to generate a 4 digit random number and add to field number 11.

Hence if 11th field is

6 digits - random number should be 4 digits
5 digits - random number should be 3 digits
4 digits - random number should be 2 digits
3 digits - random number should be 1 digits

Please assist.

rand

rand(3UCB)					     SunOS/BSD Compatibility Library Functions						rand(3UCB)

NAME

       rand, srand - simple random number generator

SYNOPSIS

       /usr/ucb/cc [ flag ... ] file ...

       int rand();

       int srand(seed)
       unsigned seed;

DESCRIPTION

       rand()  uses a multiplicative congruential random number generator with period 2^32 to return successive pseudo-random numbers in the range
       from 0 to 2^31 -1.

       srand() can be called at any time to reset the random-number generator to a random starting point. The generator is initially seeded with a
       value of 1.

SEE ALSO

       cc(1B), drand48(3C), rand(3C), random(3C)

NOTES

       Use of these interfaces should be restricted to only applications written on BSD platforms.  Use of these interfaces with any of the system
       libraries or in multi-thread applications is unsupported.

       The spectral properties of rand() leave a great deal to be desired. drand48(3C) and random(3C) provide much better, though more	elaborate,
       random-number generators.

       The low bits of the numbers generated are not very random; use the middle bits. In particular the lowest bit alternates between 0 and 1.
