Hi,

Thanks , the script worked well in ksh, now using your script each variable can be applied for each line ,
It is very helpful to me , But i am getting error while trying to use while loop or until after "eval" to get variable array's each element.
I will search the forum to get suitable result, meanwhile if anybody has solution it could be fine for me.
I should not expect more anyway i will workaround to get and if anyone knows Please do let me know.

Code:
$more test.txt
111|22|33|44|55|aa|bb|cc
dd|ee|ff|gg|ii|jj|kk|ll|mm|nn|oo|pp

Code:
$more test_script_6.ksh
#! /usr/bin/ksh
WORD=0
i=0
while IFS=$'\|' read -A WORD$((++i)); do
eval echo -e WORD$i "\\\t" $\{#WORD$i[@]} "\\\t" $\{WORD$i[@]}
echo -e "WORD2 WORD2[3]=${WORD2[3]}"
#j=0
#until [[ $j == "$\{#WORD$i[@]}" ]]; do
#echo -e WORD$i WORD$i[$j]=${WORD$i[$j]}
#j=$((j + 1))
#done
;done < test.txt

Code:
$./test_script_6.ksh
WORD1    8       111 22 33 44 55 aa bb cc
WORD2 WORD2[3]=
WORD2    12      dd ee ff gg ii jj kk ll mm nn oo pp
WORD2 WORD2[3]=gg


Code:
$more test_script_6.ksh
#! /usr/bin/ksh
WORD=0
i=0
while IFS=$'\|' read -A WORD$((++i)); do
eval echo -e WORD$i "\\\t" $\{#WORD$i[@]} "\\\t" $\{WORD$i[@]}
echo -e "WORD2 WORD2[3]=${WORD2[3]}"
j=0
until [[ $j == "$\{#WORD$i[@]}" ]]; do
echo -e WORD$i WORD$i[$j]=${WORD$i[$j]}
j=$((j + 1))
done
;done < test.txt

Code:
$ksh -x test_script_6.ksh
+ WORD=0
+ i=0
test_script_6.ksh: line 3: syntax error at line 9: `$' unexpected

tried with "while" also same error.

Thanks,
Regards,
karthikram

encode::mime::header

Encode::MIME::Header(3pm)				 Perl Programmers Reference Guide				 Encode::MIME::Header(3pm)

NAME

       Encode::MIME::Header -- MIME 'B' and 'Q' header encoding

SYNOPSIS

	   use Encode qw/encode decode/;
	   $utf8   = decode('MIME-Header', $header);
	   $header = encode('MIME-Header', $utf8);

ABSTRACT

       This module implements RFC 2047 Mime Header Encoding.  There are 3 variant encoding names; "MIME-Header", "MIME-B" and "MIME-Q".  The
       difference is described below

		     decode()	       encode()
	 ----------------------------------------------
	 MIME-Header Both B and Q      =?UTF-8?B?....?=
	 MIME-B      B only; Q croaks  =?UTF-8?B?....?=
	 MIME-Q      Q only; B croaks  =?UTF-8?Q?....?=

DESCRIPTION

       When you decode(=?encoding?X?ENCODED WORD?=), ENCODED WORD is extracted and decoded for X encoding (B for Base64, Q for Quoted-Printable).
       Then the decoded chunk is fed to decode(encoding).  So long as encoding is supported by Encode, any source encoding is fine.

       When you encode, it just encodes UTF-8 string with X encoding then quoted with =?UTF-8?X?....?= .  The parts that RFC 2047 forbids to
       encode are left as is and long lines are folded within 76 bytes per line.

BUGS

       It would be nice to support encoding to non-UTF8, such as =?ISO-2022-JP?  and =?ISO-8859-1?= but that makes the implementation too
       complicated.  These days major mail agents all support =?UTF-8? so I think it is just good enough.

       Due to popular demand, 'MIME-Header-ISO_2022_JP' was introduced by Makamaka.  Thre are still too many MUAs especially cellular phone
       handsets which does not grok UTF-8.
