Re: Macro Question

A dot after &mo in the first case is a style choice. With no addtional text to append to the macro variable resolved value notthing much happens.

In the second case you do not want to add two dots at the value would resolve to have_Aug.13 which would be treated as a library named have_Aug and dataset named 13. You generally only want to have one dot UNLESS  you are appending another dot for syntax purposes such as in liberary.dataset or filename.ext.
