Re: variable ending with ^@

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.

Subject:  variable ending with ^@

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.)
