Prepared statements?

I'm starting to use CLSQL and I'm noticing that the more recent
versions make no mention of prepared statements, the methods
"PREPARE-SQL", "RUN-PREPARED-SQL", etc. although they are in the goole
cached versions of the CLSQL on-line doc. Also, no mention in
clsql.pdf but it's there in the XML files used to make the HTML doc.

Are using prepared statements still OK, or is there a different way of
doing things now?

Thanks,
