"abc.cgi" has $in{'idx'}. 
here is program flow
abc.cgi->abc.cgi on form .submit->abc.xsl on form submit->xyz.cgi
redirect->abc.cgi

[download]
"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.

In reply to variable ending with ^@ by himanshu.padmanabhi
