I've written some generators and gotten SO confused quoting quotes. I wrote some helper functions - one, oddly enough, is called Q, and simply puts single quotes around any string. So instead of: 'title:=''My Title'';' I write 'title:='||q('My Title')||';' This looks more complicated in the example, but when you have lots of this stuff, it winds up more readable. I also use REPLACE a lot.</p> I’d never seen the Q quoting mechanism, thanks for pointing it out. I’ve written some generators and gotten SO confused quoting quotes.
