chop a data file into rows

A very naive question... I have a file which has many rows and many columns and I would like to chop off the rows and create a new file per row named after the first column of every row + 1. The data files look like:

Code:
# Donades de la trajectoria de la particula 60001
# 1:T 2:Massa 3:Rx 4:Ry 5:Rz 6:Vx 7:Vy 8:Vz 9:R
0.90000E+01 0.163931734859943E-01 0.149392051696777E+02 -0.115339336395264E+02 0.145814510688069E-04 -0.300543576478958E+00 0.102525159716606E+00 0.265361722995294E-05 0.188735656738281E+02
0.10000E+02 0.163931734859943E-01 0.146375942230225E+02 -0.114305801391602E+02 0.172515174199361E-04 -0.302688330411911E+00 0.104193426668644E+00 0.266770848611486E-05 0.185719509124756E+02
0.11000E+02 0.163931734859943E-01 0.143338079452515E+02 -0.113255243301392E+02 0.198788038687780E-04 -0.304894536733627E+00 0.105929985642433E+00 0.256998623626714E-05 0.182681560516357E+02
0.12000E+02 0.163931734859943E-01 0.140277833938599E+02 -0.112186956405640E+02 0.223633705900284E-04 -0.307165294885635E+00 0.107739351689816E+00 0.238643792727089E-05 0.179621219635010E+02

etc...

And the new files should look like

File Splotch4_0010_part_b.asc :

Code:
0.90000E+01 0.163931734859943E-01 0.149392051696777E+02 -0.115339336395264E+02 0.145814510688069E-04 -0.300543576478958E+00 0.102525159716606E+00 0.265361722995294E-05 0.188735656738281E+02

Where the _0010_ comes from the first entry, in bold + 1

It should be easy but I don't know how... Smilie

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
