awk summing specific lines and fields

Hi
I would like to know if it is possible to sum some specific fields.

I have this
Code:
 
x;x;x;x;x;x;x;x;467,390,611 Bytes;0.435291 GB;0.062247 GB;0.373045 GB;11,225;157
a;a;a;a;a;a;a;a;13,805,156,846 Bytes;12.857054 GB;1.838559 GB;11.018495 GB;151,063;18,933
b;b;b;b;b;b;b;b;232,797,478,723 Bytes;216.809547 GB;31.003765 GB;185.805782 GB;176,861;21,445;Parent: Line #545

I need to sum fields 9,10,11,12 except any line cotaining wording "Parent Line ...#

so currently I am doing something like grep -v -i "Parent" >new file,
then awk to print specific fields to new files,

and doing it through it.
Code:
 
awk "{s+=$1} END {print s}"

for this case desired output would be to sum only lines
Code:
 
x;x;x;x;x;x;x;x;467,390,611 Bytes;0.435291 GB;0.062247 GB;0.373045 GB;11,225;157
a;a;a;a;a;a;a;a;13,805,156,846 Bytes;12.857054 GB;1.838559 GB;11.018495 GB;151,063;18,933


Edit: adding more information:
I have a very long list nearly 1100 lines,
Each line is very similar to these

Code:
x;x;x;x;x;x;x;x;467,390,611 Bytes;0.435291 GB;0.062247 GB;0.373045 GB;11,225;157
a;a;a;a;a;a;a;a;13,805,156,846 Bytes;12.857054 GB;1.838559 GB;11.018495 GB;151,063;18,933
b;b;b;b;b;b;b;b;232,797,478,723 Bytes;216.809547 GB;31.003765 GB;185.805782 GB;176,861;21,445;Parent: Line #545

And I need to sum all fields to obtain: the total number of bytes, and GB. (while removing those lines that contain wording "Parent: Line"

For my example the total number of bytes and gigabytes, would be something similar to:
Code:
14272547457 Bytes;13.292345 GB;1.900806 GB;11.39154 GB

I get those numbers by summing all the row of fields $9, $10, $11, $12

467,390,611 Bytes + 13,805,156,846 Bytes = 14272547457 Bytes
0.435291 GB + 12.857054 GB = 13.292345 GB
0.062247 GB + 1.838559 GB = 1.900806 GB
0.373045 GB + 11.018495 GB = 11.39154 GB

Python implicitly assumes that each physical line corresponds to a logical line.
True or False?

Locale::Codes::LangFam(3pm)				 Perl Programmers Reference Guide			       Locale::Codes::LangFam(3pm)

NAME
Locale::Codes::LangFam - standard codes for language extension identification SYNOPSIS
use Locale::Codes::LangFam; $lext = code2langfam('apa'); # $lext gets 'Apache languages' $code = langfam2code('Apache languages'); # $code gets 'apa' @codes = all_langfam_codes(); @names = all_langfam_names(); DESCRIPTION
The "Locale::Codes::LangFam" module provides access to standard codes used for identifying language families, such as those as defined in ISO 639-5. Most of the routines take an optional additional argument which specifies the code set to use. If not specified, the default ISO 639-5 language family codes will be used. SUPPORTED CODE SETS
There are several different code sets you can use for identifying language families. A code set may be specified using either a name, or a constant that is automatically exported by this module. For example, the two are equivalent: $lext = code2langfam('apa','alpha'); $lext = code2langfam('apa',LOCALE_LANGFAM_ALPHA); The codesets currently supported are: alpha This is the set of three-letter (lowercase) codes from ISO 639-5 such as 'apa' for Apache languages. This is the default code set. ROUTINES
code2langfam ( CODE [,CODESET] ) langfam2code ( NAME [,CODESET] ) langfam_code2code ( CODE ,CODESET ,CODESET2 ) all_langfam_codes ( [CODESET] ) all_langfam_names ( [CODESET] ) Locale::Codes::LangFam::rename_langfam ( CODE ,NEW_NAME [,CODESET] ) Locale::Codes::LangFam::add_langfam ( CODE ,NAME [,CODESET] ) Locale::Codes::LangFam::delete_langfam ( CODE [,CODESET] ) Locale::Codes::LangFam::add_langfam_alias ( NAME ,NEW_NAME ) Locale::Codes::LangFam::delete_langfam_alias ( NAME ) Locale::Codes::LangFam::rename_langfam_code ( CODE ,NEW_CODE [,CODESET] ) Locale::Codes::LangFam::add_langfam_code_alias ( CODE ,NEW_CODE [,CODESET] ) Locale::Codes::LangFam::delete_langfam_code_alias ( CODE [,CODESET] ) These routines are all documented in the Locale::Codes::API man page.
