Padding lines in a file with newlines
Hi Guys,

I have a file as shown below:

Code:
55
6
77
8
88
98
7
85
45
544
1
33
32
13
13
23
44
11
67
87
243
56
344
23
133
1343
12
10
1155
321
15
899
654

The data is supposed to be arranged in a group of 10 values. Some groups do not have all 10 values.

So for example the following numbers belong to one group:

Code:
55
6
77
8
88
98
7
85
45
544

The following set of numbers belongs to another group but does not have all 10 values:

Code:
1
33
32
13

I would like to stuff this group with blank lines.

So my final output file should look like this:

Code:
55
6
77
8
88
98
7
85
45
544
1
33
32
13
 
 
 
 
 

13
23
44
11
67
87
 
 
 

243
56
344
23
133
1343
12
10
 
 
1155
321
15
899
654

So group 1 had all 10 values, group 2 (numbers 1,33,32,13) had only 4 values hence, padding of 6 more newlines to make it 10; group 3 (13,23,44,11,67,87) has only 6 values so padd it with 4 newlines to make it 10, etc.

Next I want to collect all these values in an array including the empty lines as a null array element.

How can I do this?

Thanks for your help.

locale::codes::langfam

Locale::Codes::LangFam(3)				User Contributed Perl Documentation				 Locale::Codes::LangFam(3)

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.
