Problem

How to use wildcards in pen table - User wants to know how to use wildcards for specifying multiple Reference Logical Names under the "Files" tab when creating/modifying a MicroStation pen table. 

Solution

In the Reference Logical Name field under FILES, use the characters .* before or after part of the name.
Examples:
.*gray.* - to find all reference files with the word "gray" in it
gray.* - to find all reference files beginning with the word "gray"
.*gray - to find all reference files ending with "gray"
