Actually you do not need the for loop:
Code:
printf "%s" "1^2^3%4^5^6%7^8^9%" |
awk '{printf("<tr><td>%s</td><td>%s</td><td>\$%s</td><td align=center><input type=checkbox name=DA value=%s></td></tr>", $1,$2,$3,$1)}' RS=% FS=^

Alternatively, since you are using bash, it could also be done without awk:
Code:
printf "%s" "1^2^3%4^5^6%7^8^9%" | tr % '\n' |
while IFS=^ read f1 f2 f3
do
  printf "<tr><td>%s</td><td>%s</td><td>\$%s</td><td align=center><input type=checkbox name=DA value=%s></td></tr>" "$f1" "$f2" "$f3" "$f1"
done

or in bash code:

Code:
while IFS=^ read -d% f1 f2 f3
do
  printf "<tr><td>%s</td><td>%s</td><td>\$%s</td><td align=center><input type=checkbox name=DA value=%s></td></tr>" "$f1" "$f2" "$f3" "$f1"
done <<< "1^2^3%4^5^6%7^8^9%"

locale::codes::langext

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

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.
