Abstract
A method for reducing programming or data errors generated by a new computer program or data set when the computer program updates or replaces an existing computer program. A set of baseline output records is generated by running the existing computer program on an input file (step 701). A set of revised output records is generated by running the new computer program with the input file (step 702). The baseline and revised output records are mapped to form an association between corresponding records (step 707). The associated records are compared using tolerance data stored in a control file to produce a plurality of difference records, a portion of which represents the programming or data errors (step 711). The difference records are examined to identify the portion of the difference records corresponding to the programming or data errors for editing the new computer program.
