Problem:
When trying to evaluate (?), a function that returns void, I get the
error "?CANNOT DISPLAY". I cannot find this error message in the
"Microsoft CodeView Utilities and Editor" manual.
Response:
This error message is not contained in the CodeView manual.
The "?CANNOT DISPLAY" error message will be displayed in cases where
the expression evaluator cannot return a value, such as a function
returning void.
