Never mind! I found my own answer once I remembered the database is SQL.
For anyone else who needs it, here's how to change a topic search table entry (I've bolded terms that you need to replace):
HalBrain.RunQuery "UPDATE
tablename SET topic = '
newvalue' WHERE searchString = '
lookupvalue'", temp
My issue was updating a "Version" entry in my KAOSSettings table, from 0.1 to 0.2 in script. So my specific command is:
HalBrain.RunQuery "UPDATE KAOSSettings SET topic = '0.2' WHERE searchString = 'Version'", KAOSTemp
As for the rest of my questions, or how to adjust entries in other types of table, I have no idea [

] But I'm happy for now.
Cheers,
Grant
