Oracle 8.1.7.4 supports CASE only in SQL. Oracle 8.1.7.4 does not support CASE in PL/SQL (even in the cursor and select into statements).
You have to use DECODE pseudo column instead. Something like:

decode(AB.EffDateStart,

            decode(AB.PeriodStatus, c_future
                            , CP.BegEndEnd,CP.BegEndStart)
            ,0 , 1)
