Thanks for all the answers
But I should have ask it differently,
and I will put in a piece of code
in order to be more specific.
I have this code:

#!/usr/local/bin/perl

use DBI;
use strict;

my $field;
my $temp;
my $i;
my $query;
my $name;
my $value;
my $glossary_id;
my $inbuf;
my %Form;
my $pair;
read(STDIN,$inbuf,$ENV{'CONTENT_LENGTH'});
my @pairs = split(/&/,$inbuf);
foreach $pair (@pairs) {
($name,$value)=split(/=/,$pair);
$value=~tr/+/ /;
$value=~s/%(a-fA-F0-9a-fA-F0-9)/pack("C", hex($1))/eg;
$Form{$name}=$value;
}
$ENV{INFORMIXSERVER} = "develop_remote";
my $database = "test";
my $dbh = DBI->connect("dbi:Informix:$database");
if ($Form{field}=~/editor_comment/){
$query = "update glossary_develop set($Form{field}) = (\"$Form{value}\") where glossary_id=$Form{glossary_id}";
}
else {
$query = "update glossary_develop set($Form{field}) = ($Form{value}) where glossary_id=$Form{glossary_id}";
}
my $rows_affected = $dbh->do($query);

and the query is no good if it breakes in to few
line in the middle of the value: ($Form{value})

Hope I am more specific now and hope you can help me
again.
Thanks.
Tsvika.
