The version of SBProlog which I have does not
implement assert, asserta, assertz correctly.
A clause containing any of the asserts often fails.
Has anyone else encountered and or fixed this bug?
Does anyone have a version of SBProlog on a SUN-3
which does not have these problems?
Are there other relatively cheap or free Prolog interpreters for Sun-3's
which I could use instead? (I'd like a version I can ftp if possible.)
Anyone have ideas about how hard it would be for
me (New to prolog, familiar with C and unix) to fix the assert problem?

It helps to mention what version you're using, and what symptoms the bug displays. -- Saumya Debray CS Department, University of Arizona, Tucson internet: debray@arizona.edu uucp: arizona!debray

Hi: While the bug is being fixed, try using $assert, $retract instead. They work on my version 2.5 (assert, retract don't). Incidentally all the builtin predicates (like recorda, recorded, erase) that use assert, and retract won't work either. If you'd like the patch code (for recorda, recorded, erase) in the interim, send me mail. Madhu
