Code flow

"abc.cgi"  has $in{'idx'}.

abc.cgi->abc.cgi on form .submit->abc.xsl on form submit->xyz.cgi
redirect->abc.cgi

"abc.xsl" passes value to next form like "<input value="{$idx}"
type="hidden" name="idx"></input>" as suggested here.

I am getting value of $in{'idx'} in final abc.cgi in above cycle.But
getting its value as "idx=14^@".

what is this "^@".I tried with chomp,chop.It still remains.
