I don't know the answer, and I suspect no-one else does either. You haven't
given enough information. It's not even clear what programming language each
of these code fragments represents. Certainly, the "^@" is coming from a
place that you haven't told us about.

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.
The string "^@" is a common way to make visible the control character NUL.
If I had to guess, I'd guess that some program in your tool chain is miscalculating a string length somewhere, or inserting a UTF16 character from page 00 of Unicode, in a place where the consumer of the data is expecting UTF8 or some eight-bit character set. (The 00 octet will look to an eight-bit application like a NUL character.)
I hope this helps. (But Michael Kay is quite right: it will help you get better answers if you provide better information about the problem.)
