There were a lot of all-in-one "office suites" for the C64. Most of them fall short, and this one is no exception. The H.A.L. System does have a lot to offer, though. The calculator program (called "HALCULATOR", of course) is excellent and the calendar/memo program is Y2K compliant. Best of all, the programs are in BASIC and easily customizable.
