SHC> I'm not sure but I think this is what you want:

SHC> ( $header{"keys"}, $header{"info"} ) = split(/\t\n/, );

nope. he is splitting two different input lines and you read in one
line.

what perl is saying is that @header{'keys'} is a literal single index in
a slice which is just wrong. a slice needs multiple keys or an array for
the index and then perl thinks it is fine.

the next problem is that $header{'keys'} is a scalar value now and split
expects to be assigned to a list. so the solution is to make a list:

( $header{"keys"} ) = split(/\t\n/, );

that way perl keeps quiet as the index and sigil are in agreement. the
() make a list so only the first value of the split will be assigned to
the hash element. everyone is happy!
