maybe so?
Code:
#!/bin/bash

step=2999
declare -i start=12109 end=start+step count=1
stop=$(awk '{if($3>max) max=$3} END {print max}' file)

while [ $end -le $stop ]; do
        awk -vA=$start -vZ=$end -vf="file$count" '
                $2>=A && $3<=Z {print > f}
        ' file
        start+=step
        end+=step
        count+=1
done

mlib_volumefindmax_u8

mlib_VolumeFindMax_U8(3MLIB)				    mediaLib Library Functions				      mlib_VolumeFindMax_U8(3MLIB)

NAME

       mlib_VolumeFindMax_U8, mlib_VolumeFindMax_S16 - maximum intensity searching

SYNOPSIS

       cc [ flag... ] file... -lmlib [ library... ]
       #include <mlib.h>

       mlib_status mlib_VolumeFindMax_U8(mlib_u8 *max, const mlib_rays *rays);

       mlib_status mlib_VolumeFindMax_S16(mlib_s16 *max, const mlib_rays *rays);

DESCRIPTION

       Each function performs maximum intensity searching.

       It uses the following equation:

       max[i] = MAX{ rays->results[j][i]
		     j = 0, 1, ..., rays->nsteps[i] }

       where i = 0, 1, ..., rays->nrays - 1.

PARAMETERS

       The function takes the following arguments:

       max	       Pointer to an array of rays->nrays maximum values of the samples in each ray.

       rays	       Pointer	to  an	mlib_rays  structure.  The data rays->results are organized with ray number (rather than ray step) varying
		       fastest. Ray number and ray step are the output of the ray casting functions. The data might have values beyond the maximum
		       step on a ray. For example, rays->results[rays->nsteps[i]][i] on ray i might not equal 0.

RETURN VALUES

       The function returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE.

ATTRIBUTES
