I can see a reason... It is unreadable for us mere mortals

What is IT?

Inside a macro definition use regular comments when you want the comment to appear in the log when MPRINT is on.  So when the comment is something that helps the user understand the steps of the program. Use macro comments to comment the macro. So comments that help the coder understand how to maintain the macro, such as why you used a particular option. Use block comments when you need to include semi-colons or unbalanced quotes. Normally in a header block that might include usage examples.

Agreed. But the example was one of the "comment out existing code" which often leads to bad things when it becomes a habit using *; within macros. Especially when & gets involved.

That is another discussion.

In the rare cases where I temporarily comment out macro code by adding a * I also make sure to add the * AFTER the % so that it actually becomes a macro comment.
