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?
