Re^2: Can't use string ("query") as an ARRAY ref error

Yeah , I have modified the code but my doubt is why it doesnot work when the query itself is "query".
it worked fine till the point where the query was like "abc" "perl" etc.

What you've showed us can't work if `$query` contains the string "`query`". To get into the "then" part, `$hash{query}` must contain the string "`query`", which will cause the following `@{$hash{$query}}` to fail. If you get into the "else" part, `$hash{query}` is set to the string "`query`", which will cause the following `@{$hash{$query}}` to fail.	[reply] [d/l] [select]
