6.8.2.1 Example

Let's say that you write a macro that copies comments from a program to another buffer. The comments in our program are preceded by a slash, so you start the macro with a search for a slash. However, not all comments are worth copying. Following the search with a query lets you decide case by case whether the search has found a comment you want to copy. Table 6-4 shows a macro to copy comments to another buffer.
