That will compare true for things like "Bob's Bank".

That is identical in result to the original dd="Bank" comparison.

That, too, would compare true for "Bob's Bank", because there are 20 
trailing spaces in the 30-character field dd.

That's better, but would still compare true for a typo such as "Bank  Of 
Bob".  (Note the two spaces between "Bank" and "Of".)
