Just as in shell syntax, the { } are used to delineate the boundaries of the variable's name. ${foobar}bas evaluates to "bas" if foobar is not set. Without the delineation there might be no way to know what variable name you wanted.number=7701 street=wyandotte bingham=${number}$street Thus "$bingham" is "7701wyandotte" in this silly example. For real-world Postfixated examples, continue reading in your documentation.
Ok, I get it now... if you had this: $foobarbas it would be looking for the variable foobarbas which doesn't exist!
Thanks
