Specifying files in an aggregate storage location is commonly used
with the FILE, %INCLUDE, and INFILE statements.  A FILENAME statement
points to an aggregate storage location such as a directory and then
in the FILE, %INCLUDE, or INFILE statement the fileref followed by the
name of the file enclosed in parenthesis is specified.  For example:

   FILENAME READ "C:\MYDIRECTORY";
   %INCLUDE READ(MYFILE.TXT);

Referencing a file in an aggregate storage location where the name of
the file contains parenthesis can cause a syntax error or may show the
submitted code in the SAS Log, but the code is never executed.  An
example of what can cause this problem is:

   FILENAME READ "C:\MYDIRECTORY";
   %INCLUDE READ("MY(FILE).TXT");

To circumvent the problem specify the entire pathname within quotes in
the FILENAME, FILE, %INCLUDE, or INFILE statement, such as:

   %INCLUDE "C:\MYDIRECTORY\MY(FILE).TXT";

This problem will be fixed in SAS 9.2.

Note:  A file located in an aggregate storage location with a name
that contains special characters must be enclosed within quotation
marks.
