Re:  variable ending with ^@
Thank you for all that help

Yes,problem is in the later part.

abc.cgi- > abc.xsl -> abc.cgi

Still finding the exact point where they get inserted.I will tell you
if I fail to.

btw,in above flow,in my 'xsl file',I am getting values filled in the
combo box from 'logic file'.
I want to choose value selected by user from combo either my 'logic
file' or 'abc.cgi'.
How can I get it?Values should be there in $in hash of 'logic file',I think.
