Description: CLALL deletes all logical file table entries by resetting the table index, LDTND ($98). It clears current serial channels (if any) and restores the default I/O channels via CLRCHN. The path to CLALL is through an indirect RAM vector at $32C. Applications may therefore provide their own CLALL procedures or supplement the system's by redirecting this vector to their own routine.
