How can I use a check box in a Base report to indicate a binary value? [closed]

I'm working with a church and am trying to print a report from a database. I want to use a check box (or filled square) to indicate the condition of a binary variable. It can be either TRUE or FALSE. Any help or suggestion would be appreciated. I do have the report extension from Oracle loaded and am using it to build reports.
