In English, I can write things like
The sign says "Stop".
The webpage said that it had already finished.
Can I likewise write
DerDas Schild sagt "Stoppen Sie".
Die Internetseite hat gesagt, dass es schon beendet hatist.
in German? IfIf not, what's an alternative construction that works?
(If I have bungled the "arbitrary filler" parts of these examples, please also say -- or edit my question directly.)
Thanks!
