OFS does not apply to few records in awk
Hi ,

I am having a problem with my awk oneliner , which for some reason leaves the first two records

Input File
Code:
$ cat file1
A1:B1:C1:NoLimit
M1:M2:M3:Limit
A2:B2:C2,C3,C4,C5
A3:B3:C3,C4,C5,C6,C7

Desired output
Code:
A1,B1,C1,NoLimit
M1,M2,M3,Limit
A2,B2,C2
,,,C3
,,,C4
,,,C5
A3,B3,C3
,,,C4
,,,C5
,,,C6
,,,C7

I am using the below oneliner to achieve it partially but i dont get why the first two records OFS does not change to comma ,
Code:
nawk 'BEGIN{FS=":";OFS=","}{gsub(",","\n,,,",$NF);print}' file1

This gives me an output
Code:
A1:B1:C1:NoLimit
M1:M2:M3:Limit
A2,B2,C2
,,,C3
,,,C4
,,,C5
A3,B3,C3
,,,C4
,,,C5
,,,C6
,,,C7

Can someone please help me understand the problem and correct the code

locale::codes::langfam

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.
