(a) No form of mechanization of accounting processes computers included can or will alter the objectives or the principles of auditing. The aims are generally to report on the correctness of the view that a Statement of any sort is presenting; the principles are that the auditor only expresses his opinion in so far as he has good grounds (from the work executed by him, or under his guidance) to accept or qualify the correctness of the Statement.
(b) No hard and fast rules can be set out in detail for any audit, least of all for the very comprehensive category of computer audits, so that no clear and simple recipes can be expected for any dealings with computer audits.
