Integrate MIN and MAX in a string
I need to use awk for this task !

input (fields are separated by ";"):
Code:
1%2%3%4%;AA
5%6%7%8%9;AA
1%2%3%4%5%6;BB
7%8%9%10%11%12;BB

In the 1st field there are patterns composed of numbers separated by "%".
The 2nd field define groups (here two different groups called "AA" and "BB").
Records are not necessarily sorted by groups like here.

For each group independently, I would need to get the max and min values at every position where there is a number and return the result in a third field like that:
Code:
1%2%3%4%;AA;1-5%2-6%3-7%4-8%0-9   #note if there is no number after a "%" it counts as "0"
5%6%7%8%9;AA;1-5%2-6%3-7%4-8%0-9
1%2%3%4%5%6;BB;1-7%2-8%3-9%4-10%5-11%6-12
7%8%9%10%11%12;BB;1-7%2-8%3-9%4-10%5-11%6-12

What I did so far but cannot manage to get the entire result in the 3rd field for each group:
Code:
awk 'BEGIN{FS=OFS=";"}

{
    a = split($1,b,"%")

    for (i=1; i<=a; i++){
        if(b[i] ~ ""){b[i] = "0"}
        else{b[i] = b[i]}
        
        if((!MIN[b[i]]) || (MIN[b[i]] > b[i])) MIN[b[i]] = b[i]
        if((!MAX[b[i]]) || (MAX[b[i]] < b[i])) MAX[b[i]] = b[i]
    }

END{for (i=1; length(MIN[b[i]]); i++)
            printf("%s",$1 ";" $2 ";" MIN[b[i]]"-"MAX[b[i]]%")
      }'

Any help would be greatly appreciated !!

locale::codes::langext

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

NAME

       Locale::Codes::LangExt - standard codes for language extension identification

SYNOPSIS

	  use Locale::Codes::LangExt;

	  $lext = code2langext('acm');		       # $lext gets 'Mesopotamian Arabic'
	  $code = langext2code('Mesopotamian Arabic'); # $code gets 'acm'

	  @codes   = all_langext_codes();
	  @names   = all_langext_names();

DESCRIPTION

       The "Locale::Codes::LangExt" module provides access to standard codes used for identifying language extensions, such as those as defined in
       the IANA language registry.

       Most of the routines take an optional additional argument which specifies the code set to use. If not specified, the default IANA language
       registry codes will be used.

SUPPORTED CODE SETS

       There are several different code sets you can use for identifying language extensions. 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 = code2langext('acm','alpha');
	  $lext = code2langext('acm',LOCALE_LANGEXT_ALPHA);

       The codesets currently supported are:

       alpha
	   This is the set of three-letter (lowercase) codes from the IANA language registry, such as 'acm' for Mesopotamian Arabic.

	   This is the default code set.

ROUTINES

       code2langext ( CODE [,CODESET] )
       langext2code ( NAME [,CODESET] )
       langext_code2code ( CODE ,CODESET ,CODESET2 )
       all_langext_codes ( [CODESET] )
       all_langext_names ( [CODESET] )
       Locale::Codes::LangExt::rename_langext  ( CODE ,NEW_NAME [,CODESET] )
       Locale::Codes::LangExt::add_langext  ( CODE ,NAME [,CODESET] )
       Locale::Codes::LangExt::delete_langext  ( CODE [,CODESET] )
       Locale::Codes::LangExt::add_langext_alias  ( NAME ,NEW_NAME )
       Locale::Codes::LangExt::delete_langext_alias  ( NAME )
       Locale::Codes::LangExt::rename_langext_code  ( CODE ,NEW_CODE [,CODESET] )
       Locale::Codes::LangExt::add_langext_code_alias  ( CODE ,NEW_CODE [,CODESET] )
       Locale::Codes::LangExt::delete_langext_code_alias  ( CODE [,CODESET] )
	   These routines are all documented in the Locale::Codes::API man page.
