How can I resolve this case of “Useless use of a variable in a void context”?

Question

How can I resolve this case of \"Useless use of a variable in a void context\"?

For example:

  my $err = $soap_response->code, \" \", $soap_response-&         


        

Answer 1

I guess you wanted to concatenate the string pieces to form the entire error message, so you'll have to use the dot instead of comma:

my $err = $soap_response->code. " ". $soap_response->string. "\n";
