Abstract
A method for storing and propagating error information in computer programs, in which a globally valid error variable is used for storing and propagating the error information, wherein for each recognized error a nonzero value for the error is added to the error variable as error information with a respective stipulated arithmetic sign, and wherein the value is formed from a discrepancy in the content of a coded variable from an expected value. This combination and integration of a separate global propagation variable with values derived from an error, particularly by virtue of detected discrepancies in the known error recognition and propagation paths using operations and operands in 'coded processing', achieves an increased propagation certainty.
