Split file using awk

I am trying to read a file and split the file into multiple files. I need to create new files with different set of lines from the original file. ie, the first output file may contain 10 lines and the second 100 lines and so on. The criteria is to get the lines between two lines starting with some characters(variable)

eg. A sample input file

DOC100
aaaaaa
bbbbbb
cccccccc
END
DOC200
ddddddd
eeeeeee
END

I need to send the lines between DOC100 and END to out.1
and lines between DOC200 and the next END to out.2

I thought I could do this using awk and I tried the following command but it didn't work.

k=grep DOC $filename|cut -c4-6
awk -v cn=$k '/DOC$cn/,/END/ { print $0 }' $filename >$outfile

Can anyone help me on this? Thanks

pkcs7

PKCS7(1)							      OpenSSL								  PKCS7(1)

NAME

       pkcs7 - PKCS#7 utility

SYNOPSIS

       openssl pkcs7 [-inform PEM|DER] [-outform PEM|DER] [-in filename] [-out filename] [-print_certs] [-text] [-noout] [-engine id]

DESCRIPTION

       The pkcs7 command processes PKCS#7 files in DER or PEM format.

COMMAND OPTIONS

       -inform DER|PEM
	   This specifies the input format. DER format is DER encoded PKCS#7 v1.5 structure.PEM (the default) is a base64 encoded version of the
	   DER form with header and footer lines.

       -outform DER|PEM
	   This specifies the output format, the options have the same meaning as the -inform option.

       -in filename
	   This specifies the input filename to read from or standard input if this option is not specified.

       -out filename
	   specifies the output filename to write to or standard output by default.

       -print_certs
	   prints out any certificates or CRLs contained in the file. They are preceded by their subject and issuer names in one line format.

       -text
	   prints out certificates details in full rather than just subject and issuer names.

       -noout
	   don't output the encoded version of the PKCS#7 structure (or certificates is -print_certs is set).

       -engine id
	   specifying an engine (by its unique id string) will cause pkcs7 to attempt to obtain a functional reference to the specified engine,
	   thus initialising it if needed. The engine will then be set as the default for all available algorithms.

EXAMPLES

       Convert a PKCS#7 file from PEM to DER:

	openssl pkcs7 -in file.pem -outform DER -out file.der

       Output all certificates in a file:

	openssl pkcs7 -in file.pem -print_certs -out certs.pem

NOTES

       The PEM PKCS#7 format uses the header and footer lines:

	-----BEGIN PKCS7-----
	-----END PKCS7-----

       For compatibility with some CAs it will also accept:

	-----BEGIN CERTIFICATE-----
	-----END CERTIFICATE-----

RESTRICTIONS

       There is no option to print out all the fields of a PKCS#7 file.

       This PKCS#7 routines only understand PKCS#7 v 1.5 as specified in RFC2315 they cannot currently parse, for example, the new CMS as
       described in RFC2630.
