Problem Characters in Filter Names
You should not use wildcards or special characters when naming a filter or you will encounter the following problems:
- Number signs (#) in filter names may cause the application to close under certain circumstances.  
 - Backslashes (/) in filter names will cause difficulty in printing reports.  
 - Asterisks (*) in filter names will be changed to percent signs (%) upon save.  
 - Ampersands (&) in the filter name may return all records in the module.  This will cause problems accessing the record set.
