== Prolog rewrite ==
[https://en.wikipedia.org/w/index.php?title=Computer_program&diff=prev&oldid=1170324682 This edit] changed the ''Prolog'' section from material I could understand to material I cannot understand. This article is general purpose. It should explain computer programs at the most elementary level possible. The prior Prolog material was elementary. The current material is complicated. Was the prior material incorrect? [[User:Timhowardriley|Timhowardriley]] ([[User talk:Timhowardriley|talk]]) 20:22, 15 August 2023 (UTC)
:Yes, unfortunately, the previous program was not correct. See the talk page for [[declarative programming]]. For example, the clauses <code>cat(tom).</code> <code>animal(cat).</code>are not correct Prolog.
