Email Attachment Wildcard

[Foriest]

What is the syntax for SAS email attachment wildcards?  I have a weekly pool of .pdf files that includes the current date in the file name i.e. CentralBook05012012 and  CentralBook05032012 where the only difference is the date included in the file name. 

How can I reference the file name with a wildcard when emailing from SAS?

I use a macro variable to fill in the date as part of the filename when I make the file, e.g. ProductTables20&filedate..pdf

The same naming convention is used in the attach statement.
