Simple scripts for Quark 3.32

I am a complete newcomer to AppleScripting in the old Quark 3.32 and I’m just trying to change some specific words in a text box to bold, and also searching for double paragraph marks and making them single. I also need to search for specific words and delete them.
I know it can be done using Quark’s Find/Change box, but I’d like to automate it a bit.
Could someone please help me? If I can get a good sample to get me going, I could handle the rest.
