expression used as a statement

Hi,

What does "expression used as a statement" mean? I could not find a reference to this message in the documentation and reading to code is more work than I am willing to do right now. Besides, someone may already have the answer.

Here are the output from gpc and the source code. Line 1219 is the call to View.

Thanks.
