Abstract
AbstractIt is often essential to know if a computer program has been altered. If the text has been provided on magnetic tape and subsequently loaded onto another computer with possible changes in the character set, the problem becomes more difficult. This paper proposes the use of a ‘parity check’ as used in digital data transmission. An implementation of this algorithm in Pascal is given together with details of how a Pascal source text can be checked for alterations using the algorithm.
